What's the best item to spend £50 on?

it would help to know what kind retailers? If M&S is an approved retailer you could use the voucher on a nice jumper or even socks/underwear - typically good quality and longer lasting. For approved supermarkets you could also get yourself a nice bottle of booze to enjoy over christmas, or as a gift for someone else. It's a bit boring, but £50 would also be a good chunk towards a food shop (for myself personally it would more than cover one) Techwise- a good charger cable or power bank? They're always handy to have but I never want to spend more than £10 of my own money on something like that haha. I'd say the best thing is to think of things you normally need or want but can't justify spending £50 on.
