CVS:

CVS brand diapers, $5.99, get a $2 ECB = $3.99
Ban, $2.99, get a $2 ECB.  Used a $1 coupon  = free
Huggies, 50% off, $8.99.  Used a $2.50 coupon = $6.49

I used a $2, a $1 and a $6.99 ECB.  My total was $4.49+tax and I earned $4 in ECB.  I'm okay with that. :o)  Though, I dooooo much prefer those $0 totals, haha.
