Decent price (cheeky)
I used to have a Canon printer and only fed it 3rd party cartridges as well, no problems for me either. I do the same with my current Epson, far cheaper than genuine inks and the results are quite satisfactory.
I have a canon printer and use 3rd party refurbished cartridges, works just fine
£49 at Tesco Edinburgh. I think this bargain may be store specific going by the yellow/black reduced barcode stickers in OP's photo....sadly ;(
I voted cold becuase Canon ink cartridges are very expensive and the printers are rigged in a way which prevents you from using copy cartridges. I switched to a HP printer whoose cartridges are cheaper.
