Interesting find
A couple more data points for you
1. I never bought cards at Kroger (safeway has always allowed me to buy cards in virtually any amounts, combinations imaginable)
2. I don't buy the colorful MasterCards
3. I sometimes buy cards at office supply stores
4. I have always seen 3760 in any location
5. I never had problems paying citi (knock on wood)
