If you're looking to pick up a new army and would like to save a couple hundred dollars, check out Maelstrom Games
Consider the following:
They have a 10 - 15% discount on most 40k and fantasy items
They offer FREE overseas shipping if the order is over £10
The current exchange, rate thanks to Britain's massive debt.
A Landraider retails for $74.50 CAD. Maelstrom lists them for £33.75.
£33.75 = $51.17 CAD
As shipping is free, this means you pay $51 for a Landraider. Americans, I think you save even more.
A friend just purchased an entire Guard army from them, saving himself $250. The only question is over import taxes. I'm not sure how high the duty will be, or if there will be one at all.
