Let’s chat: what receipts do you save?

This past week I bought some CFL bulbs to replace a few lights that had burned out.  This time, I bought name brand, since we purchased an off-brand at Walmart the time before and they only lasted as long as a “normal” bulb.  I happened to think that I should keep the pacakaging in case it doesn’t last as long as it’s guaranteed to, and noticed that the receipt and UPC is required to get your money back.

I usually keep my grocery receipts in one envelope until it gets full and then throw it away.  I’m always hoping I’ll find a rebate for something I’ve already purchased. ;)  I’ve gotten lazy lately and just thrown some of them away, though.  Like the one I needed to save for the CFL light bulbs, just in case.

I’m curious – what type of receipts do you keep, and for how long? Do you have a special storage system?  A particular rhyme or reason for saving some and not others?

Please share your opinion and strategies in the comments.  Last week we talked about what to do with extra milk, and I and many others learned a ton – here’s hoping we can share more great tips on thits subject!  If you are reading via RSS or email, please click here to leave a comment.
