There are a few potential issues with selling products through Weebly. First, there is no way to track sales or inventory. This can be a problem if you need to know how much product is selling and how much inventory you have. Second, Weebly offers very limited customization options for your products.
This means that you may not be able to create the exact product that you want to sell. Finally, Weebly does not allow you to set up payments or shipping processes through the platform. This can be a problem if you need to take credit card payments or process orders through an external shipping company. Overall, Weebly is a useful platform for creating and selling products, but there are some limitations that you should be aware of.
