From wicktron's post regarding BBB, here's an excerpt worth reading:
Some of the complaints have issues with the advertised rebate, both the catalog and web site have numerous offers for items with a mail-in rebate. Upon receiving the products the rebate application is not included in the package. Customers are told the rebate application is on the website and customers are required to comply with the program and submit paperwork that they never received. Many are denied because the product they have purchased does not have the advertised rebate, the rebate has expired, and some rebates are only good if the item is purchased with a computer. Many customers feel they have been victims of bait and switch, and are unable to return the products because the package has been open. Customers who have contacted customer service with concerns have problem with getting return calls, emails, and experience unresponsiveness and unconcerned customer service staff.
