The listing, 20 MCR points - Possible mystery bonus could get up to 50 points! has ended.
I have codes from two cases of Diet Coke. The 12 pack cases are worth 10 points each, for a total of 20 points. The problem is, I often buy much bigger cases, frequently buying the 32 pack from a discount warehouse, which are worth 25 points each. Cases in between 12 packs and 32 packs are worth 15, 18, and 20 points. I stupidly cut the codes out of the packages and just piled them up with my cap codes. Now I have no idea how much the case codes are worth, except that the smallest case I ever buy is 12, which is worth 10 points per case.
