Well, the old Arcos wouldn't do it and had all these rules about paying with cash and such but most in WA have upgraded to new machines and it's great because you can pay cash, debit and credit.
I asked the guy in Union 76 and he said that he wouldn't use zips at his station. So at the time it was perfect because I could just fill up after leaving the base and heading home.
Yeah, some of them won't accept different pins but the odd one did. Until I met FA, I would use 90210(hee) or the one for a mall down there. Then I used his zip but now, I don't have to use any. Definitely look into it! Good luck.
As for shopping, I couldn't buy a mouse online recently because I didn't want it shipped here so it wouldn't accept my card. So I just sent FA the money and he ordered it. Saved me 22 dollars!
