I recently received a rebate from Pep Boys for some things I bought over the holidays. In the past, the rebate shows up as a check, which I eventually deposited into my account. But this time (and more frequently, of late) rebates are coming in the form of a debit card.
Now, these things are kind of annoying. They are rarely sufficient to buy much (in this case, $10), and it's a hassle to pay for something with multiple cards, card / cash, etc. On more than one occasion, I put the card in a pile with my unused gift cards, and promptly forgot about it. Or I rang up a small purchase, and left a buck or two on the card. In either case, the card expires, I lose my money.
But now, I have a new Square account / swiper. I simply charged myself $10 and ran it through my Square account - and within a day, $9.72 was deposited in my bank account. The small Square fee (in this case, 28 cents) is less than the gas it would cost to run down to a bank or ATM, less than a first class stamp. And I can dispose of the card promptly.
