about 2 yrs ago I purchased a barracuda chuck from amazon,, I noticed penn state had a few things on sale which was some jaws for this chuck,,,i ordered them and today I got a email from them saying I had to prove I actually had a barracuda chuck by sending them a picture of the chuck,,that I couldn't believe,,,so I called and told the woman the model number of the chuck and told her I bought it at amazon,,she said very rudely,,that I still had to prove that it was a barracuda chuck,,im not a child and I do know the difference between one brand of chuck and the other,,,and I personally don't like the fact that I was being called a lier,,I cant speak for everyone else on here,,and im sure others will disagree on what im saying,,,but unless amazon sells it,,i will not buy it,,,at penn state you not only have to pay the shipping charges to get it to you but if something is wrong with it or you don't want it you have to pay the return shipping,,,,plus the fact of the wait time in which you receive it,,i have had to wait 2 weeks or more to get a item,,amazon ships most things free of charge and for any reason you don't like it,,they will send you a return label(free) to send it back which is free,,and you will receive your item from amazon in 2 days,,like I said said,,I cant speak for everyone else on here but being polite and taking care of the customer is first,,,i had rather pay more for a product than be insulted,,,im not trying to discourage anyone from buying from them,,,im sure some will disagree on this and that's ok,,thank you,,,lol,,just a bad day,,lol
