I wouldn't lump them in with Botach.
PSA is a small company, and given how the panic buying has blown up, it's obvious that mistakes can happen. I've had them forget a small part in the past; it was in the mail to me the day that I called them. The fact is that they still offer very good products and excellent prices; no wonder they're always so busy and out of stock on many items. The current situation just makes it that much worse.
