Possible CVS Scenario

Here's my scenario utilizing the $4 off $20 cpn (expires 4/19) :

1 Softsoap Body Wash = $4.99
4 Pantene Shampoos/Conditioner @ 2/$7 = $14
2 Wet N' Wild Eyeliners @ B1G1 50% = 2/$1.49
subtotal = $20.48

Use $4 off $20 CVS Beauty cpn.
Use two $3/2 cpns. (Pantene)
Use $1 cpn. (Softsoap)
oop = $9.48
Earn $8.99 ECBs ($4.99 on the Softsoap, $2 for every 2 Pantene)
