I always have a lot in advance, because I do a lot of photos so I want to have good quality of ink; with cannon, never disappointed! sometimes I take a cartridge or two more, depending on the flow; it's true that gun is a bit pricey, but for me this is what there is of better, when one has a canon printer; I recommend this lot (it is regularly promo), to all those who like me, are passionate about the photo ... and others too! When the delivery arrived earlier than expected, and very well protected: thank you Amazon
