I have £40 in Amazon vouchers for collecting points in a supermarket. 
I can either cash these in now and spend them, or wait a little while longer and wait to collect more. 
I have no idea what to use them on - i'm moving to Florida next year so something useful for that, but I have pretty much everything I need (except money!). (I've also got vouchers from a different supermarket i'm thinking of buying a kindle with)
What should I do with these vouchers?
If you were moving to a foreign country, what would you bring/buy?
