I signed up Advanta Business MC late last year. They had a double cash back promotion for the 1st 12 months. It is effectively 4% (after double promotion) after $50,000 spending, with no cap. I am maxing the card out every month. I have already accured over $5000 in cash back. 2 more months to go !!!

Advanta do seem to be a small company, their customer service is only from 9-9, M-F. which is unheard of.

did anyone else signed up for Advanta card?
