Hi RLTA, and welcome to SaleHoo.
Yes, shipping would need to be added to your buy price, and you could build that value into the items price if you were going with a starting reserve amount or BIN option, and then list as free shipping. Alternatively, you could add it as a separate shipping component and keep your items value lower.
That's just two different marketing options.
Other charges you would also need to take into consideration when pricing your item is a listing fee, final value success fee and also PayPal or other merchant processing fees on the payment transaction.
