The toys aren't great IMO. In robot mode Prime is good but the vehicle's sucky and Megatron has a few problems.

Target stocked them but in the postmovie rush on Transformers any that might have remained were swept away. The Optimus Prime figure was rereleased in movie packaging in a special double pack with Cyber Slammer Movie Prime. That was also sold at Targets but I haven't seen one in ages.
