Keep your eye out for mantis egg cases in the garden section - those hatchlings will need fruit flies.
(mantises are the next best things to chameleons)
It's usually later in the spring before you see them for sale - it always seems to take FOREVER when I'm all anxious & looking forward to it. I've gotten mine the last two years at a big plant greenhouse place in Leamington called Colasanti's, but I think I remember hearing that Cosco sells them? and last time I was at Lowe's or Home Depot, I noticed they had a little fridge in their garden section, for when the season comes around, they sell "beneficial insects" (bugs that will eat your other bad bugs, like for lawns, gardens, etc.) So they sell praying mantis egg cases like that too. It'll say like anywhere from 30 to 300 babies per case, I think I averaged somewhere in the middle of that the first year, last year I don't know, because it kind of got forgotten about in a tank in the garage, we kept thinking it hadn't hatched at a quick glance, when I finally checked closer to move & spritz it, I realized it HAD hatched after all, and a spider I didn't know about was living in the tank and had feasted on them all. 
I don't think it's the season yet, actually, just saying what I usually fed fruitflies to.
I will be getting more this year, but I still don't think I'll be able to feed them to the chams. I just love them way too much. They're so awesome.
