Without further ado, here is the pricing for Sam & Max: Season 1:
Individual episodes: $8.95
The entire season: $34.95
Buying the entire season gets you access to each episode as soon as it comes out on Telltale's site, and next spring you can get a CD version of Season 1 for the price of shipping. Remember, there will be six episodes in season 1, which means buying the whole season up front will save you almost $20.
