Rolling ExtraCare Bucks at CVS

Tonight I made a CVS run.

4 x $3.98 StayFree maxipads (various types apply for the ECB deal)
2 x $4.99 two-packs 6-hr. energy drinks
=======
$25.90 subtotal, $1.03 tax, total: $26.93

I used two BOGO (buy one get one free) Stayfree coupons from the 1/04 paper, and $5 ECB (expiring tonight), bringing the total down to $13.79 out of pocket, charged to my CVS gift card.

I received $17.98 in ExtraCare Bucks on my receipt when it printed.

Net imput: $18.79 ($13.79+ $5 ECB)
Net output: $17.98 ECB ((Energy Drink 2x$4.99 ECB)+(Stayfree 4x$2 ECB))
==============
$0.81 invested for $26.93 of merchandise

Year to date savings: $362.85
Year to date spending: $15.88 (saving 96% so far)

If you are a beginner to the CVS process, check out this lil' diagram I made tonight.

Hopefully it will help to give you a frame of reference for how coupons can be applied to where you are paying pennies on the dollar for household essentials (maxipads) and other random stuff (energy drinks...?).
