I was not impressed when I got the email but I suppose it is a clever tactic on their part. I did call immediately and they, of course, were willing to credit my CC but once I called they offered me free shipping when it came off back order so that saves $10 and I am still going to purchase a couple anyway so I left the order as is. 1 point for clever internet sales.
What I should do is cancel the order with the other company and capitalize on the now free shipping with this retailer.
I am not familiar enough with the community here yet to start name bashing an online retailer for shady practices without knowing if they are a member here or a sponsor of the site.
