We have thousands of suppliers on Sell The Trend so we cannot vet them all. For this we have some ratings in place to allow you to judge each supplier using various metrics. On the Push To Store page, you can see all these details in the Fulfillment supplier section. From Supplier ratings to product review, it’s all there so you can be well informed about each supplier before you add their products to your shop
Besides the rating there is also a contact link that will allow you to communicate directly with the supplier and be able to ask them any questions you might have.
