This plugin works - sort of. Upgraded to latest version. Among the things that did not work out of the box and needed repair:
- Shipping calculator did not work. I could only get it to work sort of
- Disregard shipping for this product doesn't work for single products and only sort of works for products with variations.
- Variations will not update
If you don't need any of these, then wait until next upgrade when something else will not work.
Save yourself some heartache and headaches and avoid this plugin.
