I was watching a special awhile back on the person that created Spanx. I was surprised to find out that the original Spanx and the ones they are sell at Target are the same thing. It's similar to other companies that produce not only name brand items but also store brand specific items as well.
Usually when you buy name brand items the cost is more because you are paying for the name.
