The biggest reason not to go to home Depot for fasteners or hardware is this.
Their prices are just absolutely insane, a common M6 metric nut in a four pack, $4, that's a dollar per nut. Anywhere else these are like six cents a piece.
Metric bolts $4 for a two pack. None of their stuff is marked so you don't know how high it is until you get to the register.
When I ultimately went somewhere else the slovenly attendant up front barked at me good luck with that like it's impossible to find these anywhere else. Is this what home Depot customer service has come to being screamed at on the way out the door because I don't want to purchase their out of control price Chinese hardware I guess so.
