I've never seen these before online at costco.ca, so figured I'd mention it here in case anyone else wants to check them out. I used Kushies AIO's for ds when he was younger as a cheap alternative before stocking up on a bunch of pocket diapers and inserts. There were some poop blowouts, but otherwise I couldn't complain considering the price I paid for them. There are also some other diapers, GroVia, that I've never tried.
