So good news and bad news.
The bad news is it sounds like Lightning Collection is downscaling it's waves (as per TokuTopics/JoshLightningPR) this week.
Wave 15 will be;
Turbo Red, Lightspeed Blue, and RPM Yellow.
Good news is Canadian Wal-marts seems to be Clearancing Lightning figures now. Especially the current wave. Just like Targets in the US.
The DF Green they have is the one with the glossy black paint. Not sure if that's the original release (with major QC issues) or the fixed version.
It's possible Blue Senturian may show up at WM as well.
