I have only placed a couple of orders with PAC, but I don't have any problem with them. On the 26th, I placed an order under $100, and was not charged shipping. If you looked at the site at that time, there was an offer up for free shipping, but with an end date of 6/20. I placed my order, no shipping charges were added, which surprised me. On the 27th, I rec'd an email from Mike, stating they were out of one item, and that there was an error with the shipping, which should have been charged. I was given the opportunity to either cancel the order, or pay the net difference (a very small amount) for shipping. Since the items I ordered were 25% off, I gladly paid the additional for shipping, for which I rec'd a PayPal invoice today.
Remember, they are operating with computer problems, and are likely short staffed at this time. Likely they are also dealing with an unusually high order volume.
Under the circumstances, I am sure some errors will occur, But I believe they are doing their best in a difficult situation.
I have every confidence that all orders will be filled to the best of their ability.
I am certain they are not out to cheat anyone, but I am also sure that mistakes can occur. I am also sure they will make things right. From what I see, they have been an honorable business for many years, and I see no reason that would change at this time.
