We are trying to keep shipping costs down for our customers as much as we can. We only charge EXACT shipping, sometimes the sites shipping calculators, calculate on the high side, if you think shipping is high, email us, we can double check that for your. But be confident to know, that even when you pay for your order we ALWAYS double check shipping to get you the best rate possible. If we can, we refund the overage at the time we run our shipping labels. Due to the fact we are trying to keep fees down, we are not adding in shipping insurance to the USPS options. If you would like your order to be insured you will need to purchase it. If you are using the UPS option insurance is included in their rates automatically.
