With food prices and household bills still putting pressure on family budgets, many of us are looking for practical ways to save money.
The good news is that there are plenty of simple tricks that can help reduce your shopping bill. I've personally used many of these methods over the years and have saved hundreds, if not thousands, of pounds.
If you're wondering how to save money shopping online in the UK, here are 15 tips that actually work.
1. Buy Generic and Supermarket Own-Brand Products
One of the easiest ways to cut your grocery bill is to switch from branded products to supermarket own-brand alternatives.
In many cases, the quality difference is minimal, but the price difference can be significant.
Products such as:
- Pasta
- Rice
- Tinned vegetables
- Cereal
- Cleaning products
can often be much cheaper when bought as supermarket own brands.

2. Stock Up When Products Are on Offer
If you regularly buy certain items and they have a long shelf life, consider buying extra when they go on sale.
For example:
- Toilet rolls
- Coffee
- Laundry products
- Tinned foods
- Toothpaste
Buying when prices are low can save money over the long term.
However, only stock up on products that you know you'll use.
3. Check Whether BOGOF Deals Are Worth It
Buy One Get One Free (BOGOF) offers can look tempting.
But before buying, ask yourself:
- Do I actually need two?
- Will I use both products?
- Is it cheaper elsewhere?
Sometimes a BOGOF deal isn't a bargain if the second item ends up going to waste.

4. Make the Most of Seasonal Sales
One of the best ways to save money shopping online in the UK is to take advantage of major sales events.
These include:
- Black Friday
- Boxing Day sales
- Christmas promotions
- Easter offers
- Bank Holiday sales
Planning larger purchases around these events can often lead to substantial savings.
5. Always Search for Coupons and Discount Codes
Before completing an online purchase, spend a few seconds searching for:
- Discount codes
- Voucher codes
- eCoupons
Many retailers offer first-order discounts or promotional codes that can reduce your bill instantly.

6. Use Cashback Websites
Cashback websites are one of my favourite money-saving tools.
I personally use:
- TopCashback
- Quidco
- Complete Savings
Over the years, cashback websites have returned thousands of pounds to me on purchases I was already planning to make.
Before buying anything online, I always check whether cashback is available.
7. Upload Your Receipts to Cashback Apps
Some cashback apps reward you simply for uploading your shopping receipt.
These apps regularly offer cashback on:
- Groceries
- Household items
- Drinks
- Snacks
It only takes a few minutes and the savings can add up over time. Some of the apps may be beneficial for you as below:
• Shopmium
• Shoppix
8. Buy Discounted Supermarket Gift Cards
Many third-party websites sell discounted gift cards for major supermarkets.
You can then use these gift cards:
- In-store
- At self-checkouts
- Online
Saving even a few percent on your grocery spending every month can make a noticeable difference over the course of a year.
9. Shop at Budget Retailers
Don't overlook discount retailers.
Stores such as:
- Home Bargains
- B&M
- Poundland
- Poundstretcher
- Nisa
often sell short-dated or clearance products at heavily reduced prices.
I've picked up some excellent bargains over the years by checking these stores regularly.

10. Look for First-Order Discounts
Many supermarkets and grocery delivery services offer discounts to new customers.
Before placing your first order, search for:
- Welcome offers
- Voucher codes
- New customer promotions
These deals can sometimes save £10, £15 or even more.
11. Use Cashback Credit or Debit Cards
If you pay off your balance in full every month, cashback cards can provide additional savings.
Some cards offer:
- Cashback on supermarket spending
- Cashback on fuel
- Cashback on everyday purchases
Even a small percentage back is better than nothing.
12. Check Your Bank's Rewards and Perks
Many banks now offer:
- Supermarket cashback
- Retail discounts
- Spending rewards
- Cashback offers within their banking apps
It's worth checking your banking app regularly as these offers can change frequently.
13. Check Your American Express Offers
If you have an American Express card, don't forget to check your offers section.
Amex regularly provides:
- Cashback offers
- Statement credits
- Retail discounts
I recommend checking at least twice a year, if not more often.
14. Take Advantage of Credit Card Sign-Up Bonuses
Some credit cards offer rewards or statement credits if you spend a certain amount within the first few months.
If you're planning a large purchase anyway, these promotions can provide valuable savings.
However, only spend money that you can afford to repay.
15. Send an Offer to eBay and Amazon Marketplace Sellers
Many third-party sellers are willing to negotiate.
If the option is available, consider:
- Sending an offer on eBay.
- Contacting marketplace sellers.
You might be surprised at how often a seller is willing to accept a lower price.
Final Thoughts: How to Save Money Shopping Online in the UK

Small changes such as:
- using cashback websites;
- buying own-brand products;
- checking for discount codes;

can save hundreds of pounds every year.
Personally, I now automatically check for cashback, discount codes and supermarket offers before making almost any online purchase.
The savings may seem small at first, but over time they can add up to a significant amount.
