Prime Day deals are out, and I didn't see much compelling for long time fans:
TF One Orion Pax converting helmet $10
A bunch of ReAction for $13
Bunch of One step or Battlers in the sub-$10 range
Most of the Amazon exclusive kid figure bundles are 30-50% off.
An interesting coupon I found is a "Spend $40, get $10 off" special, which includes Devastation Optimus Prime and SS86 Bumblebee, along with assorted other toys (Flying Fist He-Man, 5" Homer Simpson, Epic Hero X-Wing stood out to me, but there are many more)
