Spreezio

Since you haggle like a clueless tourist in person, this new e-service lets you name your desired discount on everything from electronics, to furniture, to shoes; just type in an item or category, dial up what percentage off retail you'd like to pay, set your location radius, and if a nearby retailer accepts your offer (partnered brands range from Nordstrom to Best Buy), you just have to print out a coupon and redeem it in person, as they've found it's far more difficult to mock you for being a cheap bastard via the Internet.
