This may be a pricing error since upon adding to the cart, it comes up as $24.74 for me on Prime Day representing a 70% discount from the $82.50 it's listed at as part of the Prime specials.
Other stores (e.g. Baby Bunting) have it for $119 (down from $149) so I'm assuming this is a pricing error. Good luck to those who get it!
This activity set/play mat seems to have decent reviews online and I was actually hunting for one! How convenient.
Awesome deal!
