The shipping rates of products on Spocket depend on the location of the supplier and your customer- and thus each product has a shipping cost listed separately.
When you add products from Spocket to your store, these shipping rates are not exported- there is no field in Shopify for individual shipping costs.
With the shipping rates for every product being different, it can be a little tricky to set up the shipping rates in Shopify.
That being said, you can choose from three shipping rate options.
Free shipping: Add the cost of shipping to the retail price you have set, in the Import List of Spocket. That way, you avoid undercharging your customer.
If you plan to ship worldwide, simply add the International shipping rate.
If you wish to have a separate shipping cost, you can go to your Shopify admin, head over to Shipping settings and then set your preferences. You can have different rates for different shipping zones too. These will be the options available to you per shipping zone:
Flat rate of shipping: Choose a shipping rate that is same for all products, so that it averages out, maybe select a higher shipping rate considering the most pricey product shipping on your store.
Price based shipping: Set your prices so that similarly priced products can have one shipping rate. This shipping depends on product cost.
