Shopify Marketplace Connect

I recommend this app for the full 100% for sell on both Amazon and eBay. Working with a spreadsheet, makes it much more easier to have a clear overview of all the details and it works! Especially if you have problems with GTIN exemption because you sell unique products without a product identifier, this app is super useful, because after the Amazon Approval for GTIN exemption, Codisto generates the ASINs for you. Besides that, if I can't figure something out, the helpdesk is super supportive and quick to respond. Just for their advice and 2nd opinions, I would pay the monthly fee, which is very affordable/fair. Thanks Codisto!
