Anyone who buys a coffee a day from their favourite coffee shop will know how quickly the cost mounts up.

With even a basic Americano costing well over £2 at most coffee shops, wouldn't it be great to get your caffeine boost for less?

Well, Starbucks is offering a 50p discount on a customer's order in return for one simple act. The coffee chain says it will give customers the discount if they take their own cup into the store.

Starbucks already offers a 25p discount for coffee-lovers who use their own cups.

But from April, a two-month trial will take place across the UK with the discount doubled.

A spokesman for Starbucks said: "In the UK we offer a 25p discount if you bring in your own reusable cup to our stores.

"From 1st April for two months, we'll be trialling an increase in the discount of our reusable cup incentive to 50p for every drink purchased in any reusable cup, with the single exception of our £1 filter coffee.

"This can be any reusable cup, not only a Starbucks one - which we sell from £1."
