CVS: Possible Head + Shoulder ECB Deal!

Here is a sweet deal at CVS. If you can find Head and Shoulders clearanced to $1.57, you can turn this into a moneymaker. The Head + Shoulders is printing a $2.00 ECB when you buy 1.  (this is not in the ad). In addition, there is a Head and Shoulders coupon in the 12/11 RP.  So here is how your deal would look:
 
Buy (2) Head + Shoulders $3.04
use $1.00/2 coupon from 12/11 RP
Pay $2.04
Get $4.00 ECB

Even without coupons, they are free. Amanda purchased 4, but only got $6.00 in ECBs, so taking a guess that the limit is 3.

*Note – This ECB is unadvertised and I cannot guarantee it. It is working as of 6:00 pm EST on 12.28.
