But savvy shoppers can pick up a surprisingly similar style water vessel for summer online – and we have a clever hack that will effectively make it free.

Online retailer Ego has a very similar tumbler to the famous Stanley Quencher that fans on TikTok and Instagram cannot get enough of, and it costs a fraction of the price of the real deal.
At just £15, the Ego tumbler boasts a durable design, a huge 1.2L capacity, a large handle and a wide straw, perfect for glugging your daily water intake.
The streamlined design comes in a selection of fun colourways, including our favourite hot pink, grey and purple shades, but popular options are selling fast.
For fans who want to pick up a tumbler for absolutely nothing, (yes, you read that correctly), all you need to do is take advantage of the latest promotion from the money-saving cashback website, Quidco.
Quidco is offering new customers an exclusive £15 bonus cashback deal when you make a purchase of £5 or more from the extensive list of retailers.
The offer includes any transactions from Ego, so all you have to do is sign up for a free Quidco account, find Ego on the cashback website and click through to buy your Stanley Cup dupe as normal.
Quidco will then track your order and pay the bonus into your account.
