Looks to me like this is only for new accounts. You pay 2.50 to get a month of eq with all the expansions unlocked and the item. I cant find any really good details on this though, I didn't get the email some have claimed to have gotten about it. I did see a link to it on eq's 11th anniversary site, go to
http://everquest.station.sony.com/eq11th and then click on the "anniversary sale" button, an ad banner comes up (only came up the first time i went there, i had to clear my cookies to get it to show up a 2nd time) saying that for new accounts you can get all the expansions and the item for 2.50, but clicking the banner just brings you to
http://store.steampowered.com/ and I cant find anything on that site that gives any solid info about the promo. Maybe it just hasn't ben added yet and the banner / emails went out a bit early, maybe its a mistake i dunno.
If one of you can post some links that show something more then this please do, id sure like a duration invis clicky.
