Whats the difference between the plus and regular card membership card holder

Not much. Just a select few savings

20% off all prescription glasses, including frames and lenses, too. Also, $10 rewards for every $500 spent, and it accumulates. $5,000 spent in one year pays for the Plus membership. Everything after that is gravy.

You earn cash on some purchases.

I get 5% off all gas purchases no matter where I buy my gas if I charge it. That's like 10 - 15 cents off every gallon.

Prescription cost only like $6 compared to $25
