I second the "Crappy Tire" reference. Not that I have had lots of bad experiences but do agree you need to shop wisely as you would at the Walmart. They will carry name brand parts and appliances but also crap at times too just to be able to have door crashers etc.

In their defense I will also say that they have been good to me when it comes to rainchecks, returns, and refunds when dissatisfied so yes, I shop there.
