People are only just finding out you don't need £1 coins to use a trolley

Turns out, you don't actually need a £1 coin to use a shopping trolley.

Yep, in news that is sure to save your Saturday shop, one TikToker is teaching us how to finesse the trolley system when you don't have pound coin laying around.

Check out the hack here:

Get ready to take notes, as supermarket hero @tasha3212 shared her hack for getting a trolley.

Taking to TikTok, the content creator explained that a helpful stranger shared the trick: "When some lady shows you this at Tesco. How am I only just learning this?"

While Tasha had access to other change, she didn't have the much-needed £1 coin which she required to unlock the trolley - or so she thought.

Stacking two 20p coins on top of each other, Tasha showed how you can simply slot them both into the slot which is usually reserved for £1 coins.

Once she pushed them into the slot, out came the lock, prompting a slew of commenters to commend the woman for trying the hack.

Some loved the helpful trick: "Fabulous," one person commented beneath the video, while another onlooker added: "I have to try that one."

Another shared their own trick, adding: "The coin ones without the tray you can use a round end door key."

While others weren't exactly convinced: "Sorry but if I haven’t got 1 £1 coin how do you think I’m gonna have 2 20ps?" And to be fair, that's a pretty good point.

While another said that it didn't work at some supermarkets: "Doesn’t work at Aldi, I ended up using my house key."

A third added that the 'hack' actually caused them a great deal of embarrassment: "Tried this today at Aldi….it didn’t work….had to get a staff member to get me a trolley out while I died of embarrassment."

Elsewhere in hidden supermarket trolley hacks, one mum realised that her shopping experience was never going to be the same again after discovering the hidden use that her cart had.

Gemma Bird, who goes by the name Money Mum on her TikTok account, showed off the two hoops at the front of a trolley in the video and revealed their true purpose - and we’re pretty shook if we do say so ourselves.
