Lexmark printer Ink - Sources

Hello all,

I'm presently doing a degree in procurement which involves extensive use of my lexmark 6690 printer. The same printer seems to guzzle ink at a very fast rate. Do any of you know of a good online source for the above brand of ink ?

My machine uses number 4 black and number 5 colour,

Thanks in advance,

Westgolf,

P.S. Mods feel free to move if this is not the correct forum,thanks.

Can you not get them refilled? That's cheaper than buying them.
This place in Galway refills: http://www.selectcartridge.com/

there is a small shop on Camden Street, near the Solus bar/pub and they sell a 'yellow pack' version of Lexmark cartridges; they are about €15 per cartridge but last about 4 times longer then normal branded lexmark cartridges; don't know the exact address but a few doors up from McDonalds cycles away from town.

I get mine from:

http://www.theinkshop.ie

It's in Cork but sells via the website also.

(I have no connection with them ... except that they are cheaper than the Lexmark shop)
