If your family is like mine there are plenty of receipts around, possibly in varying places around the house.
A few years ago I came up with a solution to our receipt problem....
This is a magnetic note paper holder. It use to have note paper in it, but once it was all used up, I started putting receipts in it when I got home from shopping. It quickly became our designated receipt bin. It is on the side of the fridge and when unloading shopping bags, the receipts are immediately taken care of. If it's a debit receipt, it is logged in the check book before it's put in the bin. I go thru all the receipts every few months and file the ones we need to keep and then the rest go in the recycle bin!
This has saved a lot of trouble when it comes to returning things, we ALWAYS know where the receipt is. It definitely works for us!
