I too made a purchce of several Items from Tactical Shotgunner, out of 4 Items 3 Arrived in a timely manner and fair Shipping charges, they answered all my questions promptly, I asked to be refunded for the Item that had been placed on backorder and they Quickly emailed me a Refund receipt.
I have No complaints and would buy from them again.
I am new here but is sounds to me that your going a bit overboard with this minor issue.
People have to deal with a lot worse things than my parts didn't ship on time or are on back order, take it easy already, life is too short, your going to give yourself a heart attack.
