I'm guessing BMFU figured out the least expensive way to ship orders? I'm not in the bike parts business ;-]
When I used to be a shipper it was all about UPS zones and the rate was determined by how many zones the package had to cross(zones 1 to 8). So if you were in the middle of the US, all states would be same distance(more or less). But my knowledge is 20 years old--back then UPS was cheaper than the USPostalService. Times change. Now I'm trying to figure out if the cheapest way to fulfill orders, or maybe use a fulfillment center which I have no experience with. Thanks for any advice!
