I always ship in the most economical manner possible. My shipping costs in each auction reflect not only shipping costs, but also the cost of the materials it takes to package them. If you do win more than one auction, I will be sure to make adjustments to your shipping charges. As to how much adjustment I make, I can't say for certain. It will depend on which auctions you win, as their weight varies. And it will depend upon your actual physical address. I've not looked this morning at whether you've bid on more than one auction at this point, but if you could tell me which items you are going to bid on/hope to win, and give me your zip code, I will give you a rough estimate of what I could ship them to you for.
