Yes, walmart offers folding sunglasses indeed and the prices around $7.88-$50.88. However, you must make clear these items are only in stores or online shops.

You can search folding sunglasses online, and then many sites which offer such ones skip out quickly. Well, Christmas is coming and promotings are provided in stores. Surprises are waiting for you. Catch it!
