Yeah, they were just changing prices. Looks like the 70-200 II is back up to $2300ish.
Glad I got another one the other day off Amazon. I have two now, but plan on selling the one I had been using the past year shortly. This way I got a brand new lens and a 'fresh' warranty, for almost no cost at all. Considering I can probably unload my 70-200 for $1975 or so now that rebates are over and resale will go back up. Not a bad deal... Second time I did this, actually. Did it last year as well and paid like $25 in the end for a brand new lens/warranty after shipping/fees.
