Um, actually, what they have done repeatedly is cancel people's pending orders - saying that the merchandise is not available - and then re-list the same merchandise at 50% to 100% markup within a day or two. This was a particularly common practice for them during some of the ammo shortages following mass-shootings.
IMO that is unethical and amounts to gouging. That is the kind of stuff that keeps me from buying from them. And it is not a one or two time occurrence either. It is a pattern of behavior with CTD. Google it.
Like I said I don't buy from them, and I am not bashful about explaining why. Others can do with that information what they will.
