Shipping charges are computed by the internal store software. Every item we sell has been weighed and as you place items in your cart, the weight is added up. Approximately .8 of a pound is added to the total for the packing materials, and the store software, using your zip code and address, goes directly to the UPS (www.ups.com) site to get the exact shipping charges for the weight of the shipment to your destination address. We add $1.00 for handling (covers costs of packing materials and UPS miscellaneous charges like the rent of the label machine and pickup costs).
You do need to enter your address information in order to see what the shipping charges will be, but you do NOT have to commit to the purchase if you do not like the charges. You are usually offered a number of choices, starting with ground delivery up to the most expensive which is AM Overnight.
All the shipments are insured and the cost of the insurance is already present in the cost that you are shown on the checkout page.
