Important shipping notes:
It is impossible to generate all combinations of orders to calculate shipping costs. Using straight weight also doesn't work well, because the first item costs more than
the incremental weight of another item. We will combine items in the same package for lowest shipping cost.
THEREFORE: We will calculate actual shipping costs for your order and bill your credit card
separately if no shipping charges have been added by the shopping cart. Please don't be offended when this happens. We are not trying to cheat anyone or otherwise sock you for a cost you didn't anticipate. For instance,
if ordering 4 rolls of sticky tape, no shipping charges will appear on your receipt. We will therefore have to charge approximately $5 separately.
