Unfortunately, I can't seem to find anywhere in my city (Edmonton) that sells adafruit products. Looks like Edmonton lacks in electronic supply stores, there aren't many. I could order a powerboost from SolarBiotics in Calgary, but their shipping would make it the same price as amazon.
I'll be waiting for all of my other components anyway, so I'll be fine with the banggood model. Can't wait to see your build when you get started
