Cartridge Group PG243/CL-244 PG-245/CL-246 PG-245XL/CL246XL are the same cartridge in refill perspective. Therefore, you should buy the cheapest one. I recommend getting them from Canon's online shop ( Click here to visit). The price is about $30 with free shipping (last time I checked). I will put Amazon's active price here for you to compare. Do not buy remanufactured cartridges because they have shorter lifespan and their cases are harder to open.
