I'm still having more than double charging. In fact, no matter how small I make the product, even .5" when it is really 3 inches, it still doesn't change the shipping charged. It should be picking the regional rate a box as the cheapest choice, but it doesn't even seem to be picking the large flat rate, which would be more than enough room. It's charging more than the cost of a flat rate .
I wish it would let me put in that I know I can get 16 jars in a regional rate a, 30 in a large flat rate, etc.
