How does a ebay listing with more than 1 comic work?

[gnat1000]

This is kinda a newb questions but I cant seem to find the answer. There is a auction on ebay selling about 100 of the same comic. I'm wanting to get 20 of them(dont ask). The auction started at $1.00 so I bidded my max as $1.00 and bought 20 of them. There is like 3 days left so how can I make sure that I dont lose this? I'm just not sure how auctions like this work. I usually deal with auctions of just one comic. Thanks

My only experience with multiple item auctions has been in BIN auctions. However, if I was to guess, I would say that it would work as a "Dutch auction" and the top 100 bids would win the books.
