The entire Just Cause franchise (both games plus DLC) is on sale on Gamersgate right now in a variety of combinations. They have a complete package that includes it all for $10.00, another one that is the same minus the first game for $7.50, or you can buy individual components of the series one by one for 75% off.
The odd thing though, is if you take the $10 price of the all-inclusive package it is more expensive than the price of the Just Cause 2 complete package plus the first game separately ($7.50 + $1.74 = $9.24).
More odd than that, is if you look at the prices of the individual components they list in each package shown in red, the Just Cause 2 items total up individually to $6, and the first game is $1.74, so if you just buy each individual game and DLC package individually it is $7.74 total and you get the exact same thing. The only difference is the 2 package deals include something that doesn't appear to be available for purchase separately as it has no price listed - "Just Cause 2 Guide (Web Access)". Presumably this is just a walk-through/guidebook of some sort that isn't crucial to the game anyway though.
Anyhow, if anyone is interested in these games, you have a variety of options to get them for as low as $7.74 on Gamersgate right now, and even less if there are DLC you aren't interested in etc.
Update: I just noticed there's another package that just contains all of the DLC for $1.75 also. With the standalone 1st game at $1.74 and the 2nd one at $3.74 plus the DLC pack for $1.75, that'd come to $7.25 for the entire series minus the game guide. Gamersgate needs to check their math methinks. LOL
Here is a link to the entire list to peruse and compare as I just did:
