Just wanted to add that I too have no consistent results with AMEX orders thru Barclay Rewards Boost. Only posting because I did 4 $1000 cards just now, business side. I submitted it, 5 minutes later went to look at my email, and got the APPROVED email. What cracks me up is that I didn't get the email, "Hey...we got your request for your purchase" <--- something like that. So this is the first time my purchase got catapulted (sp?) to instant approval. The AMEX approve team is drinking well tonight.
