Hi answrtek,
I just checked with eBay and verified that the "Buy it Now" feature cannot be used with multiple quantity auctions. I actually just tried to create a multiple quantity auction with a "Buy it Now" price using eBay's "Sell your Item" form, and I received the following message:
Please provide the correct information in the highlighted fields. Buy It Now price - A Buy It Now price cannot be used in a Multiple Item Auction. Please remove it.
If you have any additional questions or concerns, please file a support request using the appropriate link on our help page: http://www.auctiva.com/free-auction-software-help/help.aspx
