All right had a "doh" moment. Try this:
17.94 - 6 St. Ives
1.99 - Kashi
1.50 - coke 20 oz
-4/20
-5 crt
-6 st ives
-1.99 Kashi
-1.50 coke coupon - thanks to a mycokereward code! Could use any .50 candy bar or some other "freebie" after coupon item to push it over $20!
$2.94 OOP or using ECB's and receive back $5

Ta-da, made it work!
Good suggestion on how to use that St.Ives $5/$15 CRT! Shoot no man.coupons here for St.Ives (and I'd searched the thread but didn't see internet ones??), decided to just go for the 4 emery boards as part of the Sally Hansen-Lacross $5 ECB offer. I'd previously bought 4 Sally Hansen nailpolishes but they were clearance priced (50% off) and didn't qualify, but it's OK because they made for free filler in conjunction with the CVS $4/$20 coupon and 2-SH $1 coupons:
Today's trip:
2 Lacross emery boards: $1.79 x 2
2 Lacross emergy boards (larger ones, as no more $1.79 ones): $1.99 x 2
1 photo printed to send to grandma: $0.29
1 Reese's (balance ran negative & grabbed this as kids with me): $0.44
Less B1G1 1/2 off Lacross -$0.90
Less B1B1 1/2 off Lacross - $1
Less Sally Hansen/Lacross $1 off 2 coupon, found near polishes - $1
Less Sally Hansen/Lacross $1 off 2 coupon, found near polishes - $1
Less $2.99 ECB
Less $1 ECB
---------------------------------
OOP = 40 cents + 2 cents tax
Received $5 ECB.
Not as much fun as using the $4/$20 or $10/$50 coupon too, but couldn't pull anything together while keeping oop under a buck.
Thanks for the reminder about the CVS advisor. Did once get invited to do a survey but then never got the survey (checked my junk folder, no deal) so am keeping fingers crossed that will get another invite in the future -- I'd even do for free.
