I've been doing a little research for my local club on sources for the cardboard bird carriers people use to carry their newly purchased birds home. We thought we might be able to get a quantity discount or even a free perk from a seed company, but I haven't been able to find anything like that.
CeDe used to give away bird boxes, but they tell me that was years ago

I have been thinking of just buying plain cardboard boxes and can get those for 21 cents apiece. We tape our boxes anyway so closing wouldn't be that much different. A few holes poked and good to go.
Does anyone have any other ideas - or know of somewhere I've missed? What do you all do?
Thanks for any ideas!
