i have been in buisness for many years,shipping all kinds of stuff by ups and by truck.
heres the real deal on shipping.
What your read on ups's website about shipping cost does not carry over to the shipper,to have ups come to your shop everyday cost you,you pay them to stop in,cost vary,depends on where you are.
then you have tape,boxes,employees,scales,etc,etc. it all adds up.
at my shop we add 70% to every ups charge to help cover all those extra expenses,we keep track of every transaction,and at the end of the year we are always in the hole on shipping.
we refuse to ship usps because the post office is 30 miles round trip away from the shop,and then you have the wait at the counter while those wonderful employees screw around.
i have a girl that does my shipping,it takes her from 9 until 2 to get it done,5 hours at $15 per hour,plus workmans comp. ,vacations etc.
if your in business and you dont charge enough you will be unemployed soon.
