I would like to use USPS flat rate shipping for 3 flat rate box types (small, medium, and large) based on the total weight of the items in the cart. So, for example, if the package is:
0 - 2.99 lbs - small flat rate box price
3 - 10 lbs - medium flat rate box price
10+ - large flat rate box price
I would like the shipping to be automatically selected and NOT display the other options, so I won't have someone who has ordered items that weigh 12 lbs and should be in a large box trying to select the small box price.
Can someone help me figure out how to set this up or point me to the right extension that does it all? I'm so tired of banging my head up against this shipping wall!
