SirPrimalform: I just heard back from Telltale support and they're refusing to honour their collectors' DVD thing. I'm really pissed off about this because as far as I'm concerned I'd already paid for it, I just hadn't paid the shipping yet. If they won't send me my disc then I'm asking for a refund.
I asked Telltale support about this and they answered:
Unfortunately, we currently no longer offer the disc versions of our older games on our website (currently this offer is only for The Walking Dead: Season 2 and The Wolf Among Us). Purchasing the digital games from our website did not inlcude the disc version, but it allowed customers to then purchase the DVD version for free if they decided to purchase that version as well (pay only shipping and handling).
Technically that's true, you still had to buy the discs for "free" in order to get them. If they don't offer the discs anymore, the bonus of being able to buy them for "free" is worthless, but probably no breach of the contract. So I fear we're out of luck. :/
