How to Womble (and make £100's at the supermarket)

supermarket receipt tricks

What is wombling?

Womblers scour supermarket carparks, bins and trolleys for these receipts, and then collect the receipts with money on them to nab the rewards for themselves.

Here's the thing:

Once you have collected the receipts, all you have to do is use the barcodes on the receipts in online or in store.

Why should you womble?

  • Supermarkets are now competing more than ever for your custom.
  • When you shop at a supermarket, you’ll often find that will offer you incentives to keep shopping with them in future.
  • These incentives are often in the form of supermarket points or money back on your next shop on your receipts.
  • A lot of people can’t be bothered to cash in on these incentives (or don’t realise) and throw the receipts out, or leave them at the till or in their trolley. By doing so, they are literally throwing away money.
A wombling example:

Judith Wenban testified to the benefits of wombling, as she found a receipt worth £6.50.

She told the Telegraph that ‘it was left in a shopping basket.

If you saw £6.50 on the floor, you wouldn’t leave it there, would you?

As I’m tidying up other people’s rubbish, I have no shame in that.’

Which supermarkets does this work for?

Asda - Price Guarantee

Asda Price Guarantee

Here's how it works:

At Asda, you simply enter the code that’s on the receipt onto its website and it will give you the difference if the value isn’t 10% cheaper at ASDA than Tesco, Sainsbury's, Morrisons or Waitrose.

You now need to have an Asda Groceries Home Shopping account to claim your vouchers.

Tesco - Price Promise Guarantee

Tesco Price Promise guarantee

How does it work?

Much like Asda, at Tesco you need to enter the code on your receipt onto its website. It will then calculate if the shop would have been cheaper elsewhere and it will refund you the difference in vouchers if it is.

So if you spent £15, but you could have done the same shop for £11 elsewhere, Tesco will refund you £4 in voucher form.

The guarantee is only available on comparable grocery items that are either exactly the same or of similar quality.

Is this legit?

The Supermarkets don’t love it, but are warming up to it.

Here's the kicker:

It doesn't matter who is actually buying the groceries, because all you have to do is enter the code from a valid receipt.

If you do want to do it, we’d suggest to be discreet and don’t shout about it at the till, but if you are asked, it's best to honest.

This doesn't just work at supermarkets!

You can use a sneaky trick to get free lattes, biscuits and more at Costa too! Just use other people's receipts to earn yourself free coffee.

All you need to do is pick up a card in store and register it online, or download the app, once you've done so you'll get 100 points free (that's worth £1 already). You can then get points every time you buy something from Costa, earning 5 points per £1 spent.

So when someone else buys something from Costa and doesn't use their card you can take their receipt to the cashier and get the points they missed out on loaded onto your card!
