How do I charge a shipping rate based on quantity?

You can not charge a shipping rate based on quantity.

In Shopio, there are 2 types of shipping rates:

1. Price-based
2. Weight-based

This means Shopio calculates the total price of the order (or the total weight of the order). There is no quantity-based shipping rates but here's what our shops do as a workaround:

Example:
Basically, you're going to set up a series of rates for each price range (or weight range).
If you sell socks and they all weigh 0.5 pounds each, and you want to charge $5 per sock for shipping, then you create 10 or more weight-based rates like so:

• 0 lb to 0.5 lb $5.00
• 0.51 lb to 1 lb $7.00 
• 1.01 lb to 1.5 lb $8.00 
• 1.51 lb to 2 lb $9.00 
• 2.01 lb to 2.5 lb $10.00 Etc.
