I just won a purse on ebay from a seller that lives in Canada. The STANDARD shipping charge comes to an amount of $ 45 and on her page she states that it is an additional fee for $5 (for insurance protection). Then she msg me and said the $ 5 insurance was for tracking the item only, and told me if i wanted full insurance protection it'll be an additional fee of $ 20. I just go another email today from her saying that she'll go to the post office to make sure how much shipping is w/ insurance. and in her msg she states that it could get expensive. (meaning maybe more than $20 on top of the standard $45 !). My question is, can she just name any price she wants for shipping cost? im confused!
