Another +1. I’m going to provide a free sample for one of the items in my new store (not live yet don’t bother looking). A little bummed to discover this still isn’t in the core product. I’m still in the free trial period, I guess I could look at other options, but would really prefer to stay with Shopify as it’s a known name.
