How to Save Money Shopping Online in the UK: 15 Tips That Actually Work

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:

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:

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:

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:

You might be surprised at how often a seller is willing to accept a lower price.
