I'm working on modifying my shipping rates and running into a bit of a snag.
I'd like to set it so that if an item weighs less than 13 oz, or costs less than $30, first class shipping is available.
Conversely, if an item weighs more than 13 oz, or costs more than $30, only priority shipping is available.
The issue I'm running into, though, is that some items could weigh more than 13 oz but cost less than $30. In that case, it shows both shipping options, and customers will, of course, choose the cheapest option.
Is it possible for me to set up multiple parameters in this way without having to set individual rates for each product?
