OK now this is cheating a bit, but it works :) I did itmyself the other day and scored the Ministry of Sound 2010 Annual for around $5 total (it's not even out in store yet)
Buy this album http://www.bandit.fm/service/lookup.do?fArtistId=409429&mpWi… it's considered an album and so you get free $20 credit as part of this promotion: http://www.bandit.fm/about/promotion-freecredit?id=LinkTK-Fa… (of course you get the album as well whether or not you like it)
You have to pay on credit card and not use any credit that already exists in your account
The $20 is automatically applied on your account to spend how you want! If anybody can find anything else that's considered an album that is cheaper, please tell!
great find!
