Ok, so i know this is a bit of a nerdy one (& excuse the bad i phone photos!), but I'm one of those uber organised types.
I bought this 2 years ago & have to say its been one of the best ways to organise all my receipts & expenses!
Its divided into months
And each month has an envelope for you to store your receipts & a space to write the details for each receipt on the front.
I tend to put them in once a month or so, it makes it so much easier to reconcile at the end of the year.
AND you don't end up with mountains of receipts all over the place each July!
