Hobby Figures review for Nabu for Google Shopping Feed

Seems to be working well, just started using it but so far seems much better then the Shopify app which was giving me troubles with GTIN numbers not transferring over. A few products have had issues but that is on my end and the app shows what the issues are which is nice As a new startup the fact this is free is great, although I wonder if it will eventually be a paid app - even if it does hopefully it'll be a reasonable price, especially those with a large list of products
