Amazon sells them, but the Zero model (the smaller one) is typically very hard to get and is usually 1 per person. There is a company called Arrow that sometimes has them really cheap (they rarely go on sale) where I got 2 for $40 shipped overnight plus they sent me a free Pi Zero W. I feel like I ripped them off as it was an unbelievable deal. I wish I bought more.
