Walmart Reusable Shopping Bag, Foldable Grocery Tote Bag, Blue

I decided to give these a try today since nothing can be worse than wasting my money on so many brown bags! By the time I receive the items from the store, my family has ripped or dropped items from a ripped bag when unloading the car or helping the drivers! So, I am blue bagging it now - the only problem I am having is how do I use the blue bags for each subscription I have for groceries with Walmart? I know there has got to be something set up with them other than me buying 5 more blue bags next week, or one would hope so!! Please drop a note and let me know what you do? Thanks, Trish
