From time to time, I receive eBay 10% off purchases under $100 due to some disruption in an auction on an item I'm bidding on. I'm not that active a member, probably using the site a couple of times a month on average, yet this has still occurred on multiple occasions. The coupons' expiration dates are just a few weeks out, so I usually don't have anything to spend them on. What to do in this situation? Buy a gift card to a retailer like WalMart or Whole Foods. These are readily available at face value with free shipping. Save yourself $10 in 60 seconds.
