If anyone is still looking for one in the U.S., Micro Center has Raspberry Pi Zeros in stock (and has almost continuously since they were released). The only catch is you can only get them as part of an accessory kit. The kit includes the Pi Zero, a Mini-HDMI to HDMI cable, a micro-USB On-The-Go cable, and a micro-USB power adapter.
The kit costs $24.99 (USD), so there is definitely some "extra" profit in there, but it's not a bad price and most people starting with a Pi Zero will need the cables anyway.
