Shipping costs can be brutal.
It depends on where its going, how much insurance you buy, how its shipped and whether or not you pack it in your own box pay to have it boxed with spray-in-place foam, etc...
Those little packing/mail box stores charge a premium for convenience, so if you can ship it from your employer's shipping dept. you will save.
I paid about $60 to ship a set of forks to the midwest.
Sending my forks and shock to Factory Connection from CA to New England cost about $150, but I got gouged by a Mailboxes etc... franchise, so paid for convenience, box, packing material and $3,000 insurance (replacement cost for already revalved shock and Paioli forks). To contrast, return shipping cost from FC was $60.
