[RBS] Unneeded Canon printer cartridge?

[Yitzchok & Hasha Lavi]

Our printer (Canon Pixma ip4500) has been erratic lately and I would 
like to decide whether to continue trying to get it to work properly, 
but one of the ink cartridges is empty now and I can't do anything with 
the printer.
If you have a Canon PGI-5BK cartridge which you don't need and are 
prepared to part with, even one which is only partially full, please let 
me know.
Similarly if you have Canon CLI-8 cartridges those would be welcome as 
some of those are almost empty too.
Thank you
Yitzchok
