Trouble with Green Giant CAT reported.

Areas are reporting that the ad is a misprint. the correct CAT deal reported is as follows:
09/05 - 10/02
buy 4 get$1,
buy 6 get $2,
buy 8 or more get $3 oyno

I'ts going to be a YMMV with the store handwriting you a CAT out on purchasing three using the ad as evidence.

So this is what it looks like using the confirmed CAT deal reported:

buy 6 = 5.94
~ (2) $1/3 ( non-doubling stores)
~ (2) 0.60/3 (doubling stores)
= 3.94
Get $2 OYNO
= 1.94 for 6 boxes or 0.32 each.
