BP used to play the lower price for cash game here. IIRC Arco and BP are related. The problem was their cash price, was the same as everyone else's any payment price. Now they are same as everyone else for the last 7 or 8 years. Once vacationed in CA, and the ARCO we went to was cash or debit card only, and they had a 3¢ surcharge on the debit card price.
