Ok, so the guy that just bought your 65 pound 36 by 36 inch product lives guess ???
Yep you got it, about as far away from you as possible without leaving the country.
Now for the tough part answering the final e mail.
"I won the ...ITEM... how big is it ? what does it weigh? how much is postage to butt munch india anywhere USA"
It gets better though, that 65, 36 by 36 package of yours that when you checked online was going to cost $100.00 to ship, somehow turns into a 75 pound by 42 by 42inch oversize overweight $200.00 to ship package between your garage and the USPS center (how do peanuts and cardboard become so expensive?)
Great, now I have to pass the good news on to my customer, He was a little shook up when I told him $100.00 now I have to explain how the shipping cost doubled in the space of 20 mins, even though I have the receipts I still feel like a con man trying to squeeze a few extra bucks out of the deal.
So the moral of the story is, if it sounds to good to be true it usually is .
There are many factors that increase the price of shipping, before you give your customer a shipping quote, (unless its a basic envelope or small box) avoid those embarresing moments and let the pros do it down at the U.S Mail .
