8 for the price of 1

[HA_DA_JA]

Has anyone taken advantage of the IK Multimedia Sampletank Promotion of buying 8 Expansion packs for the price of 1?
Finishes on June 6th. It was a no brainer as the Euro is down at the moment and only Euro $40 for these seemed quite realistic.
Whats the deal with all these companies releasing group buys at these prices.
Anyway I have bought into it but I am not sure which expansions tanks to download.
They are split into 2 different sections.
There are the loop to a particular genre and then are the multi samples.
Which are more useful?
Multi samples can be used only in the free provided Sampletank program as they are an stw fiel but the loops can be used anywhere.
The multi samples can be used whatever way you like but if you dont necessarily like the loops then they arent much use - are they?
Does anyone else use these or have bought into these and can shed some more insight on the matter?
Cheers
