I'll share my little experience with Sam's once again!
Sam's Club had to pay for fixing my car before.
I had a Mustang GT, it had Super 44 Flowmaster mufflers & it sounded off very nicely,
and the little jerk who "just had to pull it in" couldn't handle it and fish tailed it into something that caused a good sized ding in my rear fender.
I will NEVER buy tires or anything else from Sam's again after having to deal with the situation & the way that they handled it!
