$3.85 at Costco in Moore, but think you have to be a member. My wife goes there and we are members but last time I was there I left being frustrated with their pumps.I didn't have the Costco card or some BS.
Yeppers...
...both Sam's and Costco require membership and having one's card to initiate the transaction. If I remember right, Costco used to NOT accept Mastercard. However, that was about 3 years ago, so that might have changed.
