My go to place to get my Gearwrench warranty is Fastenal always a no questions asked. Tried to get Advance Auto Parts to get my warranty done once they ask for a receipt till I ask for a manger only to find out that they didn't have the ratchet wrench in stock
IMO their sockets are definitely better then Craftsman. For example one of the guys at the shop was using a Craftsman 10mm or 8mm and could not take out a bolt an was asking around for an extractor instead I let him borrow the size he needed in a Gearwrench socket and it took it right out no...
I've had good luck with tooldiscounter.com as long as you order an in-stock item. Otherwise it take however long for the mfg to get the part to them. Same thing goes for ntxtools.com
