Buying generic medications online can save you hundreds a year-if you know where to look. Too many people just click the first result on Google and overpay. That’s not smart. Generic drugs are chemically identical to brand-name ones, but they cost 80% less on average. The problem isn’t availability-it’s finding the real deals without falling for fake pharmacies or hidden fees.
Why generic drugs aren’t always cheap online
Not all online pharmacies are created equal. Some charge the same as your local pharmacy. Others slap on shipping fees, require minimum orders, or hide charges in the checkout. A $10 bottle of metformin might turn into $28 after tax, handling, and "express delivery". You need to compare prices across multiple sites, not just one.Google Shopping shows up first for most searches, but it’s not always the cheapest. In fact, in 2025, Consumer Reports found that Google Shopping only showed the lowest price 58% of the time for common generic prescriptions. The rest? Either inflated, outdated, or from sellers with poor ratings.
The best tools for comparing generic drug prices
You don’t need to visit 10 websites. Three tools do most of the work for you.- Google Shopping: Still the biggest. It pulls prices from over 1.7 million retailers monthly. Use it to get a baseline. But don’t trust the top result-check the third and fourth listings too. Many small pharmacies rank lower but offer better deals.
- PriceRunner: Dominant in Northern Europe, but works well for UK users too. It factors in VAT and delivery costs automatically. For a 30-day supply of lisinopril, it often shows prices 15% lower than Google because it doesn’t hide taxes.
- Shopzilla: Less known, but better for niche pharmacies. If you’re looking for less common generics-like bupropion or clonazepam-Shopzilla often has more independent sellers. One UK-based pharmacy reported a 37% sales boost after listing on Shopzilla, meaning more competition and lower prices.
Here’s what these platforms actually show you:
| Platform | Price Accuracy | Verified Sellers | Shipping Included? | Best For |
|---|---|---|---|---|
| Google Shopping | 64% | Low | Often not | Common generics (metformin, atorvastatin) |
| PriceRunner | 81% | Medium | Yes | UK/EU buyers, tax-sensitive shoppers |
| Shopzilla | 78% | High | Usually | Less common generics, independent pharmacies |
PriceRunner’s edge? It adjusts for UK VAT and calculates delivery from the pharmacy’s actual location. Google doesn’t. That’s why a $12 bottle of sertraline on Google might be $16.50 after tax and shipping-while PriceRunner shows it as $13.50 all-in.
How to spot a fake pharmacy
There are thousands of illegal online pharmacies selling counterfeit pills. They look real. They have professional websites. They even have fake reviews.Here’s how to tell the difference:
- No license info: Legit UK pharmacies display their GPhC (General Pharmaceutical Council) registration number on their homepage. Click it. It should link to the official regulator’s site.
- No physical address: If the contact page says "email us" and nothing else, walk away.
- Too-good-to-be-true prices: A 90-day supply of lisinopril for £5? That’s not a deal-it’s a scam. Real generic prices range from £8 to £18.
- No prescription required: In the UK, all prescription meds require a valid prescription. Any site that sells them without one is breaking the law.
Bizrate’s verified purchase ratings help here. Only people who actually bought from a pharmacy can leave a review. That cuts fake reviews by 78%. Look for pharmacies with 4+ stars and 100+ verified reviews.
Real savings: What you can actually save
A 2025 Consumer Reports study tracked 8,500 UK shoppers buying common generics. Here’s what they found:- People who compared prices saved 18.7% on average per prescription.
- For high-cost drugs like insulin or antidepressants, savings jumped to 30-40%.
- Those who used PriceRunner or Shopzilla saved 22%-vs. 14% using Google Shopping alone.
Example: A 30-day supply of generic amoxicillin costs £12.50 at your local pharmacy. On PriceRunner, you’ll find it for £8.99 from a verified UK pharmacy with free delivery. That’s £4.51 saved-every month. Multiply that by 12 months and 3 prescriptions: £162 saved per year.
Pro tips for smarter shopping
Don’t just search and buy. Use these tricks to get the best deal every time.- Set price alerts: Google Shopping and PriceRunner let you track a drug. You’ll get an email when the price drops. Works great for long-term meds like levothyroxine.
- Check pharmacy ratings on Trustpilot: Look for at least 50 reviews. Avoid places with "5-star reviews" that all say the same thing-those are bots.
- Use browser extensions: Install Honey or Keepa. They auto-check if the same drug is cheaper elsewhere while you’re on a pharmacy site.
- Buy in bulk: Most pharmacies offer discounts for 90-day supplies. If you’re on a stable medication, this cuts your per-pill cost by 15-20%.
- Verify the pharmacy: Go to the GPhC website and search the pharmacy’s name. If it’s not there, don’t buy.
What’s changing in 2026
New rules are coming. The EU’s Digital Markets Act forced Google and others to label paid ads clearly. Now, you’ll see "Sponsored" next to listings from big chains that pay to be at the top. That means smaller, cheaper pharmacies can rise in the rankings.Some platforms are adding sustainability scores. PriceRunner now shows the carbon footprint of shipping from each pharmacy. If two sites sell the same drug for £9, pick the one with lower emissions. It’s a small win-but it matters.
Blockchain verification is starting to appear. Startups like PriceCheck are testing systems where every price and review is stored on a public ledger. No tampering. No fake listings. It’s still new, but if it scales, it could wipe out scam pharmacies for good.
Final advice: Don’t rush
It takes 5 minutes to check two platforms. It takes 45 minutes to learn how to use price alerts and verify sellers. But that 45 minutes could save you £200 a year.Don’t buy the first generic you see. Don’t trust a site just because it looks professional. Use the tools. Compare. Verify. Then buy.
Generic drugs are safe. They’re regulated. They’re effective. But the online marketplace is full of noise. You need to cut through it-and you can, if you know how.
Are generic drugs really as effective as brand-name ones?
Yes. Generic drugs contain the same active ingredients, in the same strength and dosage, as brand-name versions. They’re required by UK and EU law to meet the same quality, safety, and effectiveness standards. The only differences are in inactive ingredients (like fillers) and packaging. You won’t notice a difference in how they work.
Can I trust online pharmacies in the UK?
Only if they’re registered with the General Pharmaceutical Council (GPhC). Every legitimate UK online pharmacy must display its GPhC registration number on its website. Click the number-it should link to the official GPhC directory. If it doesn’t, or if the pharmacy doesn’t require a prescription, avoid it.
Why is the same drug cheaper on one site than another?
Several reasons. Some pharmacies buy in bulk and pass savings on. Others have lower overhead (no physical store). Some include shipping and tax in the price; others add it later. PriceRunner and Shopzilla show you the total cost upfront. Google Shopping often doesn’t.
Is it safe to buy medications from outside the UK?
It’s risky. Medications from outside the EU may not meet UK safety standards. Customs can seize them. You won’t have legal protection if something goes wrong. Stick to UK-registered pharmacies. Even if it costs a few pounds more, you’re protected by UK law and the NHS supply chain.
What should I do if I find a drug that’s way cheaper than others?
Be suspicious. If a 90-day supply of a common drug like atorvastatin is priced under £5, it’s likely fake or stolen. Real generic prices for this drug range from £10 to £18. Check the pharmacy’s GPhC registration, read verified reviews, and compare on PriceRunner or Shopzilla. If it still looks too good to be true, it is.

Wow, this is actually useful-rare for Reddit. I’ve been using PriceRunner for my lisinopril since last year and saved nearly £200. The VAT inclusion is a game-changer. Google Shopping? Don’t even open it unless you like surprise fees. 🤦♂️
