got a new mattress about 6 years ago. Payed hundreds for it. Don't remember where I bought it. It has a ten year warrantee. Threw away the reciept, didn't think it'd be an issue. two years in and I've flipped it multiple times. we're not overweight or anything. Not been used as a trampoline - honest. Nor have we been at it like rabbits
. The springs have been painful to lie on for years. I have other high expenses which mean I don't know if I can buy a new one for a few months yet. Savings are for more important things.
Rather than keeping batteries that dont work in drawers and the instructions for that DVD player you don't have anymore - I suggest keeping your reciepts for things like mattresses. Don't let this happen to you
