Telltale Collection... Hot or Not?

I'm debating pulling the trigger on the Telltale Collection
Isthereanydeal - Steam
Isthereanydeal - GMG
This is a substantial savings over the combined MSRP of all the games. I know that the base price has been increasing as the number of games included increase as well, and that prior to these price increases it has seen higher discount rates. And, I only own 1 of the games! Since none of us can predict future discounts, what do you think? Buy or hold?
