After finding a product I want to buy, how do I add it to the cart and submit an order?

1. Hover over the target product card, and an "Add To Cart" button will appear in the center of the card. Click it to add the product to your shopping cart. 2. Repeat this action to add all the products you want to purchase to the cart. 3. After confirming all items are added, click "Shopping cart" in the top right corner to open the shopping cart, review the contents, and submit the order.
