Thanks everyone, I've done a little more research, and it has helped seeing some of the Black Friday ads starting to appear. Unfortunately, the Fitbit appear to be a popular item for "in-store" deals. But at least I know what the really good deals are, and I think my plan will be-order one from Kohls when their Black Friday ad goes live early in the week. While I will probably be at full price for the Fitbit, I will be able to get $30 in kohls cash, which will put take my price down to $100, and I shop there on a regular basis, so I will be able to easily use the kohls cash on something.
So, now that I know my target price for the Fitbit charge is $100, if I see it anywhere at that price earlier, I will pick it up. I simply refuse to be at a kohls store (or any other retailer) when they open on Thursday to get the really great deals, and I work on the Friday, so no opportunity then.)
Thanks for the suggestions everyone!
