I've bought some things in the Sam Ash and also in the Guitar center closest to my home. I'm on record and in the 'computer'. Does this make any difference when returning merchandise within the 30 day return policy period. Like if the item has a dent or scratch on it. Will the sales people be more or less likely to look the other way? Does it matter at all? I bought a floor item and I want to return it but I see a dent that I don't know if i bought it with or if I did it.
