>>>Are there any cheap ink places?
Loads - but if you were foolish enough to buy a printer that uses a single cartridge for all colours, rather than a somewhat dearer printer that uses separate cartridges for each colour, you'll never get them really cheap.
I deliberately chose one of the dearer Canon printers because I knew that I'd be able to get compatible cartridges cheaper for it than for the less costly printers (which use a single cartridge for all colours). So I pay just 20 quid for 4 complete sets of all 5 cartridges from my preferred supplier (and I could get them even cheaper elsewhere), with inks that produce excellent prints.
This is where I get my compatible inks from
http://inkredible.co.uk/
and I'm happy to give a recommendation to that excellent supplier. (Try looking there to see how much they charge for inks for your own model). However, as I've indicated above, there are other (even cheaper) firms out there as well; try looking on eBay for them.
