Someday we're going to see the minute-zero swag/collectible/promo item listing on eBay, I swear it. Two bottles from this morning's BioShock 2 beachcomber event are on the auction site, going for up to $56 and $76 as of early afternoon.
According to the listings, both are sealed and still have their posters inside. Here's one description.
This is one of the very limited Rapture Wine Bottles buried in the sand at 10 different beaches across the world, the last of which just ended in Santa Monica. This bottle contains 3 posters, one a Rapture propaganda poster, the front with a powerful image of a fist and the words "Welcome to Rapture". The back contains propaganda pertaining the ideology behind Rapture. The other two are humorous posters containing information about two of the exciting plasmids to be featured in the upcoming sequel.
If you were nowhere near one of the beaches, or couldn't make it, well, now's your chance to own an ... advertisement. Enjoy.
