Shipping Prices

[phonehome]

I've noticed some orders have shipping prices of $28.00, some $18.00 and some $15.00. The javascript dynamic pricingshows an $18.00 shipping charge for all meds, unless free shipping is selected.


Am I missing something? How can I get the scripted pricing infoto show accurate shipping prices?

cod is an extra $10 that explains the $28.
