Costco will allow you to bring the item back for up to 1 year no ???'s asked. Was shocked to find out this goes for furniture as well. Does not apply to electronics.
It use to apply to electronics, but people were taking advantage of it. costco does extend the warranty on electronics for I believe up to 2 years though.
Don't be so shocked. Costco still makes money doing this.
Craftsman tools are built real well, other tools are cheap crap. if you use the cheap sockets on any application that you overtorque the nuts and bolts, you end up wearing out the sockets before the actual nut you remove. And the next time you use it, you end up striping the bolts because your sockets were all shaved off. Not a good thing if you work on cars.
