The policy is that you need a receipt because of people like below.
This is a very old thread I know but in case others end up here I wanted to pose a statement/question.
If Pittsburgh, or any brand tool, coat hanger, knife, etc, offers / has a lifetime warranty and a person takes said item in for exchange what difference does it make where or how the person obtained it?
If someone buys 3 Pittsburgh impact sockets at a yard sale for $1.00 and exchanges them for 3 new ones, or an individual was the original purchaser of the same 3 sockets and exchanged them it's the same thing. The warranty goes with the product and not who bought it first.
Some may say it's being deceitful in some way and I say no. What if you bought a set of Pittsburgh sockets and you used them 5 times, then they sat in your toolbox for 10-15-20 years and you died and your son or daughter ends up with all your tools, they go to use the sockets and it breaks,they go to exchange it. They are not the original purchaser but the socket should not have broken on it's second use so the son/daughter are only utilizing the option that the company has in place which is a lifetime warranty. Both examples given,neither are the original purchaser but that's what the company offers so why does it matter who was the original purchaser?
If HF/Pittsburgh has no problem with it then why are you down on this guy for doing it?
Another example. What if you bought a set of metric impact Pittsburgh sockets and never used them and 6 months later you went to use them and noticed the set did not have the size you needed so you went to Tractor Supply and bought a set of Dewalts for the job. You then sell me the Pittsburgh set for $15 a week later,but you have no receipt, I use them 2 days later and one breaks. In your eyes I'm wrong for going in to HF to exchange it? I wasn't the original purchaser but the item has a lifetime warranty and broke on first use. But even if it was the 432 nd use it does not matter because they believe in and back that item with a lifetime warranty.
