My Bass Pro Shop credit card accumulates reward points. Not sure if they're all the same, but my reward points go away at the end of each year so in my case it's use them or lose them. If you're not buying items from Bass Pro, you generally earn 1 or 2 percent instead of 4 percent. It's still better than nothing I guess.
You can use the points on Bass Pro's website as well. They track your points, so when you go to 'check out' you'll be able to enter the amount you have toward your purchase. I just cashed my points in on Dec 28th, and the item I purchased ended up being on back order. They let me cancel my order and sent me a gift card for the value of my points. Pretty good deal.
