Just over a year ago I wrote a post which shows how to disable free shipping on a per product basis. That's really useful for stores that like offering free shipping on just about everything everything and want to disable it one or two items. But what about people in the opposite situation? You might have one or two really tiny items like bookmarks don't want to charge people $5 for flat rate shipping.
I figured it was time to revisit this and write a snippet that helps these people out. We can use the shipping classes built into WooCommerce combined with just a couple lines of code to make it really easy to mark any number of products eligible for free shipping.
