If an item's defective, you shouldn't have any problems shipping it back for a new one, at the cost of the company. But unfortunately, not all sites are created equal. Understand a site's return policies before you buy anything. Just because you buy something online, doesn't mean you don't get a warranty. So be aware of what a product's warranty is before you buy it.
Many sites offer full or limited warranties on their items.
Full warranties mean return costs are covered, and a full refund or replacement will be offered if your item is not working. A limited warranty, however, can mean hundreds of different things with hundreds of different expiration dates. It's a good idea to know the specifics of an item's warranty before you buy it. If a site doesn't post any of this info, give them a call or drop them an e-mail. Avoiding Scams For every great legitimate Website you visit, chances are there are 2 or 3 illegitimate ones looking to scam you.
