I don't know about GC's but the BP station by Hewlett-Woodmere Library on Broadway is full service and doesn't differentiate between Cash/CC Prices. This usually means paying somewhere between Cash/CC prices at other stations but I've sometimes seen it the same as the cash prices at the 3 gas station intersection of Peninsula Blvd and Mill Rd.
I ended up buying some gift cards at the sunoco down the 9. They still have same cash and cc price and their price is usually around everyone else's cash price
i just bought bp gc's at shoprite now that it's Q2
Hmmm BP in lkwd is now one price for cash and credit.
