Hi cgmartine,
To answer your questions:
1. "if I use the Swipe & Save Good Sam Club discount card and a generic charge card, I get 3 cents off." Yes, when you use the Good Sam Club membership card, you get 3¢ off & you can pay with your preferred form of payment.
2. "If I use the Pilot RV Plus charge card and the Good Sam Swipe & Save card, I get 4 cents off. Is that correct?" No, you don't use the cards in combination, you use one or the other. The RV Plus Charge Card requires an application process through Pilot Flying J. Once approved for that card, then, yes, you can use the RV Plus Charge Card and save 4¢, required form of payment is the RV Plus Charge Card.
3. "I have two VISA cards from Good Sam. One is red and is stamped as RECREWARDS and has the Good Sam logo, while the second card is also stamped as RECREWARDS, but has the Good Sam and the Camping World logo. Different account numbers. Why two VISA cards? I will pass this question along to the Good Sam Camping World Visa team to respond.
Sincerely,
Good Sam Club Team
