New to the shopify world and need a little help

[streetmonkzero]

Having issues with pricing my products. I just have a few questions 

1. How do you find the cost of the item you're selling for Shopify

2. How do you "create" inventory in your store when drop shipping for Shopify

If you are dropshipping you will find the cost from some wholesale websites like aliexpress or from where you are sourcing. 

To create inventory: From shopify go-to products and create a product then you will find the inventory section where you can set up your inventory.
