Back in May I traded in items to the value of around £45. The very same day, I bought an XBOX 360 HDD which left around £20, for which a new voucher was issued. I hid the voucher somewhere so my little brother wouldnt nick it but the thgin i pretty stupidly forgot where I hid it. Would there be a chance I could take the receipt for the orginal £40ish trade in and use it to buy something for the value of £20 or even better if iwas cheeky, £40?
Also could two vouchers be used on the same purchase?
