The Home Automation thread is now basically a 1:1 ratio of places to find vinyl and actual home automation discussion, so I'll try and tease some of you over here because this is something that could be of interest.
My favourite spots in Edmonton:
Find Edmonton (5120 122 St NW): Mostly unsorted stock, but almost everything (including collections) is $1
Wee Book Inn (10310 82 Ave NW): Again mostly unsorted, but things are priced accordingly. $5 for Zamfir in case you haven't found one for free yet, and $20+ for the ones you're actually looking for
Old Strathcona Antique Mall (10323 78 Ave): Excellent and organized collection, but you'll pay $$$ for some of it.
