Is it still taken from your available balance?Mistakes do happen!
Has the items shipped?
I bought some stuffs at cowboom.com on my AMEX Delta Gold card last month. The charges (a total of ~$550) were showed up as pending charges but after 10 days, they were finally fell off without posting to "recent charge" category. My question is: Is this free money? Or eventually, AMEX (or cowboom) will find this mistake and correct it?
Seems like something is off on Amex's side of things. One would think they audit their records every so often and would find this. Keep fingers crossed that they may not say anything.
Personally I think cowboom made some mistakes at their ends. Other purchases made around the same time from other sites were posted as normal. Just 3 charges from cowboom were disappeared.
