Making a thread since most people probably don't check the Indie / Limited / Obscure release thread and considering this game is not released yet, this is probably the lowest it will be in the immediate future.
Skybound is running an SDCC 30% off sale on their store, the upcoming The Walking Dead: The Telltale Definitive Edition release is included at $34.99 (msrp $49.99, $49.99 at Amazon at time of post).
This release includes ALL of the series content on disc, per Skybound:
You can stack promocode NEW10 for an additional 10% off which takes the price down to $31.50
Free shipping is offered, and atleast in my case I was not charged sales tax (I do not know where they are based from for charging it or not)
