Worlds Greatest Llc review for Retail Barcode Labels

Trying to drop ship and cj dropshipping products dont have barcodes, anything printed on demand doesnt have a barcode, pretty much trying to sell on line is impossible. I tried to make barcodes so i can sell products on walmart using this app and it gave me 8 digit barcodes that do not fit on google, facebook, or ebay. Really misleading and stupid. After 2 hours of trying to figure it out turns out it doesnt work for its intended purpose. They should call it fake barcode labels to keep your store organized. If u need upc codes stay far the fuck away from this app.
