This is a very low shipping price for such a heavy item to ship and it’s low in general from the usual .95 and up shipping prices usually seen on supplement bottles.We’ve done some shipping price split-testing at Creative Thirst on these type of free plus shipping offers before and it is difficult to make the numbers work at such a low shipping amount, plus from our tests it has not moved the needle enough to win over a higher shipping price.This is similar to the traditional bump add on and up sell strategy used in free plus shipping offers.
