If you've been thinking of buying something on eBay—maybe, say, some sweet new PC hardware—today might just be the day to do it. Until midnight ET today you can get 20 percent off purchases through a single-use coupon code. 

You can opt for women's shoes, patio furniture, or a nice new vacuum cleaner if you like. Personally, I think you'd be better of focusing your attention on PC gaming: Keyboards, headsets, mice, maybe even a game or two. Basically anything with a buy it now option: Tee up your purchase, apply the code, and it'll knock 20 percent off the top.
