Simple way to put a few dollars into savings painlessly

I'm obsessive about saving money, I get more joy out of depositing money than I do from spending money, so every little rebate check, refund check, whatever it is I put it into savings .If you are a couponer like me you know rebates can be a part of couponing, so I always have small random checks coming in the mail from one rebate or another. Save them up for a little while (not so long that they expire) and then deposit them into your savings. You lived without the money for that long so you may as well save it right! It might only be a few dollars here and there but it adds up.
