Halloween // Looking to amp up my display this year

I need to amp up my front yard display for this coming Halloween, I have a giant spider from home depot and some webbed-up skeletons and lighting. This year I want to add a fog machine with a cooling unit to keep the fog low. I'm not sure what brands are trusted etc.

I'm looking for other ideas and more spiders?

What shopping sites or products can you recommend to find good deals on off-season Halloween merch?
