Someone's listed 10+ qty of Advanced Docks for just $129.99 plus $16 in US domestic ground shipping.

Not affiliated, just looking for docks and found this listing to share. Looks like 4 have been bought already.

Certainly looks like a great deal (I'm not affiliated with the seller either). As of this posting, they seem to have 81 more available.
Just a word of warning (to avoid confusion). The auction states

Expansion Slots: 1x ExpressCard/34

There is no ExpressCard slot on the Advanced Dock. He's probably referring to the 5/6-in-1 card reader.
