Seller cancelled/refunded the order after giving a bogus excuse that the warehouse that they purchase from said that the brackets didn't pass inspection. I ordered the same brackets from multiple sellers at the same time and all but one who did fulfill the order cancelled for a similar reason... "Wherehouse issue".
This is the problem with drop-ship sellers. Many list that they have the item and then if is sells from the one person that DOES have it, they can't get it and make up a story why.
