Personally I would like to see the largest savings on real wooden stands.
The deals on tanks are good, but I doubt that is where the majority of the expense is for most aquarium setups.
For anyone wanting a standard size glass box, this is a good deal.
For anyone wanting a mostly complete setup to run right now, this may not be the best deal for you.
If you don't mind used, you can get some incredible deals out there. (Earlier this year I picked up a 38g full setup for $40 or so at an aquarium society meeting, also have a stack of drilled and plumbed 10g tanks that were $1 each... etc)
Vincenia, knowing what all was included in the kit might let people better know what an awesome deal it was (If it wasn't a staff only discount you might be able to plug your store and let others share the joy).
What would be more useful here would be suggestions of other good deals, to turn these tanks into usable setups, rather than just a glass box of water.
