First Ebay Sell

I put up my first item on ebay I want to sell. I’m not sure if I did everything right, but I tried my best. I’m selling a full-size, Sation Nail Lacquer that came with my ipsy bag. I didn’t like the product, and only used it once. Might as well sell It. I put bidding at 1.00, idk if that’s a good or bad thing. But, I’m learning.

The only thing I’m confused about is figuring out shipping cost. Does anyone know how to configure the cost just based on your zipcode?
