I do surveys and swagbucks on my spare time so most of the time I have vouchers or try to decide which voucher I should go for.
I ordered now 70£ of Sainsbury's gift cards to go in the store and buy 70£ of WHsmith giftcards (I know, a bit of a hassle) and I will add to that 20£ of Whsmith from a mobile phone app that bakes me money

= Kobo Glo for 9.99
P.S. I think I am thick, don't understand that unethical rambling thing...
