There are four costs envolved in computing the selling price on Ebay.
1. Insertion fee.
2. Value fee.
3. Cost of item.
4. Shipping.
This is using 'dropshipping' and not warehousing anything.
The first three I can figure.
You know your supplier's zipcode.
How do you figure shipping when you do not know where your buyer is?
Any ideas?
