customs and duties, need help!

  1. hello....
    i just have a really quick question about customs and duties.
    im planning to purchase a bag for $825.00 on eBay, and the bag is coming from Italy. the price is really good for the bag, but im concerned about the customs and duties that i have to pay for when i receive the item. does anybody have any idea? if they charge me like $300 or something (or more!), i will definitely reconsider buying this item. pls help! thanks!
