I bought my first pack of Doritos last night, and while I haven't emptied the bag, there doesn't seem to be any code at all. Is it supposed to be printed on the inside of the bag, or is it a separte insert? Yes, it is a "specially marked package", and claims to be worth 200 points.
Just as a heads up the rules state that you can only have 1000 Codes "and/or" 150,000 points. So if you are only entering low point value codes then you may hit the maximum number of allowable codes before you hit the maximum number of allowable points. Though I'm not sure if anyone is really planning on buying 1000 bags of Doritos in the next couple months
The rules also state that you can be sent a free code for every self-addressed stamped envelope you send to the contest's address. Have you tried that yet? Any idea how many points that gives? Assuming that you can get 100 points for the price of two stamps, that would be the most efficient way to collect points.
