I just received my Blue Business Plus card today via UPS. I followed mia's instructions and added this card to my existing AMEX accounts. One sign-in for all cards. I did notice, however that there is a foreign transaction fee on this card of 2.7%. Too bad I didn't notice this before. I was going to use it to pay off a vacation booked through a Canadian company. My spend would have been completed with one purchase. I may still use for that purpose...... I hate having that minimum spend hanging over my head.
