Currently we just offer USPS and we offer First Class (if available), Priority and Express.
We have a lot of products that are under 13 ounces and shipping First class works out great. It's only around $2 bucks
$50 or more we offer free domestic shipping with the use of a promo code.
I have weighed all of products and we use Endicia Label Server API to estimate the cost. We are pretty accurate.
