I'm wanting to buy an Amazon gift card for a friend that I don't know too well and is quite a new friendship, so just seems like the safest option (doesn't drink alcohol). I'm looking at options and I'm not sure what is the appropriate amount? Does £10 look really shit? £20 then seems a bit much... is £15 a happy medium? Maybe I'm overthinking this, but I really want them to think it is nice and not some shitty half assed thing, although I doubt they will be expecting anything.
