+1 for Pirateship.
PS rates depend on sender supplied package info...dimensions and weight.If those are inaccurate, the rate may be off......................
you have to weigh it i always use bathroom scales or weigh myself with and without parcel , then width depth and lenght, if you can keep it under 48 inchs it is huge discount, I am sure i have been off on some guns i posted but have never heard a thing. easy to print also if you screw up you can get a refund then and start all over, this part i did not like is they use a refund as a credit which for me works because i send a lot but for someone that just occasionally post his money is in credit until he post again. Shippo uses fedx and personally do not like them,i have had to pay for a rifle and several stocks they broke they lost a rifle, they broke a stock on a hatsan galation in a hard case, so i use pirate ship my self you will have a choice of prices from usps and ups, doesnt cost a thing to look and certainly will save you money.
