Will I receive customer support like I'm used to?
Not quite. If you buy something you don't end up liking or you have what marketing people call "buyer's remorse," sell it on Craigslist or at a garage sale. It's likely you'll make money doing this and save everyone a hassle. If the item doesn't work, first, find out what you're doing wrong. Yes, we know you think the item is bad, but it's probably your fault. Google your problem, or come back to that product discussion in our community and ask other people if they know. Try to call the manufacturer and ask if they know. If you give up and must return it to us, then follow on to the next FAQ entry.
How do I return a defective product?
Unless we specifically tell you not to, call the manufacturer of the product you bought. You will likely get a replacement of a new model or better item from them. If we still haven't dissuaded you, email firstname.lastname@example.org with your woot order number, the name of the product you are returning, and the detailed problem with the item. We will respond with return authorization by the next business day. Because we aren't likely to have a replacement in stock, you should be prepared for a refund-only option if that's all we can do. Know that return freight will be at your expense. Again, you will probably get a better deal from the manufacturer, or whoever else handling member service for that product.
