For example they could be Name brand cloths from Sears or JCpenny which is right from the manufactuer, then you have TJ MAXX or Marshalls which sells the same name brands, but with a bad lot #, defects in the stiching, or just over stock. Shit even where i work sells shitty stuff like "Shark" Products which almost all of them return due to defects. But we also sell name brand stuff right from the manfactuer and is high quality.
THere is always a chance with gettin somthing from walmart that its an overstock or somthing along those lines. Peformance parts from Wally World... no chance on my end.
