Consider that a recent spot search for “Diet Coke” revealed a range of options—at a similarly wide range of price points, thanks to the army of third-party sellers who operate through the site. At the high end was a $91 multipack of cans that worked out to a per-can price of over $2.50. Most people know that’s not a normal retail price, but if you didn’t already know—or simply weren’t paying attention—you could overpay by a huge margin. So first, use your common sense. Hit that “buy” button only after you’ve evaluated the price critically, even clicking around to a few other retailers for a sense of scale before committing.ae0fcc31ae342fd3a1346ebb1f342fcb
