We're experiencing an odd issue with our Magento store: the calculated shipping price disappears when ordering more than four tires for some reason. This is such an odd issue, I'm not even sure where to start.
Here's how to replicate:
- Go to http://tagmotorsports.com/pirelli-trofeo-r-991-gt3-458-speciale-488 and add two of each tire to the cart.
- Estimate the shipping and tax by entering in a country, state and zip code.
- It will return a shipping quote for four tires just fine.
- Change the quantity of tires to anything beyond four and update the cart.
- The FedEx shipping quote disappears.
I think it may have something to do with input settings, but I'm not even sure where to start at this point. Looking through the FedEx shipping method settings didn't reveal anything immediately that might be contributing to this issue.
Any help will be super appreciated. Thanks.
