The Content Paradise front page has a link "First Friday Bazaar Sale", which will give you a list of all products included in the sale. Poser 8 will appear there, but it will only be available for a short time because they limit the number of copies sold at the discounted price.

Some have also said that the discounted price appears on the product page where they have the different options (platform, full or upgrade, etc.) listed, but I haven't verified this.

So you may have to keep refreshing the list of all FFB products. Keep an eye on the number of products which is at the top of the list. When that changes, chances are that Poser 8 has just been added. Then you can use your browser's Find function to locate "Poser" in that list.

I haven't actually seen Poser 8 at $1.99 though, this is all based on hearsay.

By the way, if someone got a coupon for a free copy of Poser 7 during the "Treasure Hunt" last month, that coupon will also work for Poser 8. I know because I got my P8 that way :)

Edit: as someone pointed out, they say at Facebook that they'll post a notice there when Poser 8 goes on sale so keeping an eye on them there is probably a good idea.
