RE: Did you take advantage of Black Friday?

I was talking to my wife about this last night saying that it's impossible to know if something is actually any cheaper unless you've known what you want to buy for a while and know the original price. The annoying thing is that the things I want to purchase never actually go on sale. I sometimes wonder if websites use cookies and algorithms to manipulate prices. Maybe that's too "conspiracy" type thinking, but it feels that way sometimes.
