These are typically deeply discounted rates for services offered by local businesses (meals, custom-made shirts, museum tickets, Pilates classes, etc.).Once you enter the specific city you're registered in, you'll see that day's deal, the retail value, the discount, and your savings. You click on the deal to buy it and then they email you the "groupon," which you redeem when you receive your service.There is a small catch: If not enough people sign up for a given deal, it doesn't happen.

Near as we can tell most of the deals go through, and there's no cost if one doesn't, so the downside is minimal.
