Considering an Amex Platinum, and was wondering about this.
I have a BCP, and for Yearrrssss have used it for gift card purchases at the grocery store.
Specifically I buy 400-500 a month in Gas Station cards (because the cheapest station around is debit or gift card only), and occasionally gift cards for birthdays too.
I've never had a problem, though admittedly I usually do try to "hide" my purchase by mixing in some groceries too so it isn't just an even $400.00. Wondering if this means my habit will transfer without issue to Platinum card, or if maybe they handle it differently for the BCP card.
I intend to ramp up to $1500-$2000/month if I can. Wouldn't mind having a years advance worth of gas money.
