Green Man Gaming have the early access [MMX] listed for $29.99. Also one can apply their 20% discount vouchers and get the game for $24. Strangely enough they don't offer a download or give any hint how you can use the game before its release. Fortunately they give you the 2 keys, which you can enter in uPlay and get MMX EA and MMVI with them.
Price is regardless of region.
