Where in Southern Ontario are you located? If in Essex County, there are some local stores that sell feeder crickets in 500 to 1000 count boxes. While the prices per box are perhaps a bit more than ordering online, the lack of shipping charges makes them cheaper in the long run. Send me a PM if you want more info.
Have you considered starting to breed your own feeders (eg superworms, etc.)? From reading your other posts, your beardie is not big enough for supers yet, but might be by the time you have a good sized colony built up in four to six months. Superworms are easy to get but a bit more involved to get started. Roaches are tough to come by in Canada, but are very easy to get going if you can find them.
