hello, I already checked this page, but it is still not enough and it is too complicated for the vendor.
Especially in this part
“Cost:
Example:
20 + ( 3 * [qty] ) – A base shipping cost of $20 plus $3 for each item in the cart.
15 + [fee percent=”5″ min_fee=”2″] – A base shipping cost of $15 plus 5% of the order total, which is at least $2.”
In addition, I would like to create the product directly by code, how can I link with the seller?
Thank you
