The amount I spend on any gift for someone depends entirely on how well I know them. If it was an engagement gift for my brother & partner I would spend up to £60, but if it was a friend from work then I'd spend £10-£15. I hope that helps a little! Remember, it's not about how much you spend at he end of the day, it's how much thought you put into the gift. The more appropriate it is for the recipient(s), the more they will apprecciate it.
