Not sure if this is the right place, or if it has already been noted somewhere. Big Bad Toy Store has listed about 20 TF items on sale for Botcon weekend (added to their clearance page). You can see them here:

Of particular note is the TFC Perseus set (Shattered Glass Hercules, I believe?) that is $200 off. Thought it might be of interest for those who collect SG stuff.
