I know that not everybody (meaning practically nobody) comparison shops to the extent that I do. Therefore you might go into Staples or Office Depot and think that USB cables normally cost $25-35. This is at least a 100% markup. They are assuming you don’t know any better, or are buying it with a larger ticket item like a printer, and in contrast it seems less expensive. And you’re too lazy to buy it elsewhere. On top of that, I see they’re trying to carry only top of the line, gold plated cables (which might have a .000003% performance gain), so you don’t have any choices. At Staples, they go a step further and gouge you for their store brand! You’re not even getting a name brand like Belkin.
Just so you know, using pricegrabber.com you can find a longer cable for less than 1/2 the price. I just purchased a 16′ Belkin USB 2.0 cable for under $10 shipped at databazaar.com. This is 60% longer and over 65% cheaper than Office Depot and Staples. And I earned AAdvantage miles from databazaar.com in the process. Yes, I have to wait a few days for my cable, but I probably could have shipped it next day air and still have saved money.
