I'm using the Paypal IPN module to handle my orders, and I have shipping set to a flat $2 for orders under $10.
This works fine inside of my website, but once it gets transferred to paypal, wierd shipping values show up:
# of items | Shipping price
1 - $2
2 - $4
3 - $3
4 - $2.66
5 - $2.50
6 - $2.40
7 - $2.35
8 - $2.26
9 - $2.25
10 - $2.24
Quantities of the same product do not effect it. Say I add 10 of one product, and then 4 different ones, the shipping cost would show up normally on my website, but then once transferred to paypal would show $2.50 for shipping instead of the flat $2.00.
So, does anyone have any advise on how to solve this?
