CVS Deals - 3/23

I made a quick stop to CVS on Wednesday at lunch time. It was a nice day and I wanted to get out for a walk. I picked up some things that sounded like a good deal, but now I have my self second guessing. I paid more than I normally do for shampoo/conditioner, but it is Nexxus, so does that still make it a good deal?

Transaction #1
1 - Allegra Allergy
1 - Nexxus Conditioner
1 - Caramel (filler)

-$2 Allegra IP
-$3 Nexxus mfg coupon

Paid with $10 and $3 in ECBs and $1.23 OOP ($.11 + $1.12 tax). Earned $6.99 ECBs.

Transaction #2
1 - Nexxus shampoo

-$3 Nexxus mfg coupon

Paid with $6.99 ECBs and $1.16 OOP ($.50 + $.66 tax). Earned $10 ECBs.

Why are the Nexxus conditioners so much smaller than their shampoos? Am I the only one that uses conditioner faster than shampoo?
