And if for some reason you haven't, get pumped for more 80%-off laser hair-removal and two-for-one California rolls than you can shake a stick at. Be mindful, though, of claims that these types of business models can be harmful to small businesses, and that customers may be less satisfied with their purchases. And that 60% off tantric beer-brewing classes might seem like a great deal, but it's not *necessarily* something you would have thought to buy in the first place.

(Also it should go without saying, but if you're paying someone for a service, always tip on the original price.)
