Deal on Canon cli-8 8-color multipack inks for Pro9000

[PhotoMoose]

Amazon is selling the Canon CLI-8 8-color multipack ink tanks for the Pro9''' for only $54.99 (free shipping as well). This is quite a bit lower than I've seen it for recently. $6.87 per cartridge.

Let me know if you can typically find it at this price or cheaper.
