Hi.

Our programmer said this is most likely a corrupted cookie. If you go to the vendor store page HERE and use the ADD TO CART green button directly under the thumb in the vendor's store, don't clck the thumb to go to the product page, it will add to cart for you. Then if you wanted...to just double check..you could delete it from your cart there. And then go to the product page and ADD to CART normally.

See if that works for you.
