CVS Scenario with $/$$ coupon!

Today in my email I got a $5/$30 coupon. Here's a scenario I worked out...

5 Oreos (or other cookies/crackers) - $5
2 Johnsons Buddies soaps - $1.98
2 Toothbrush packs - $6.99x2
2 bottles of All - $6.49
1 Smart Rinse - $3.49

30.94

-$5 Nabisco coupons
-$2 IP Buddies coupons (these might be adjusted to $1.98)
-$2 All coupons
-5/30

16.94

-12 ECBs
-4.94 on gift card

Get back $13.98, 3.49 (small profit that probably will be counteracted with sales tax)

BUT I don't know what the odds are of either easily accessible CVS having 2 of the toothbrush packs in stock (I think last I checked the store I'm going to first didn't have any). And without those packs I can't come up with a better deal. I do have a coupon for a free Cascade rinse product (around $3) and a free box of Honey Bunches of Oats (around $3) but I don't know if CVS carries either one and while they would get my original total up and my OOP down, I wouldn't get back any ECBs - the toothbrushes are the key to that. And then I'd have a $13.98 ECB to spend next month, when the deals don't look that great. SO. I might not do this at all - my plan pre-coupon was 5 boxes of Oreos for free and MAYBE the All.

One more:

5 Oreos
2 Buddies
1 Listerine
4 Dove bodywash ($5.29 each)

31.63

-$5/$30
-$3 bodywash (I only have 3 $1 coupons left)
-$5 Oreos
-$1.98 Buddies
- $12 ECBs
$4.65 + tax on gift card

Get back $9.49 ($6 Dove and $3.49 Listerine)

Not great. I had another scenario with 2 Bruts but I already got 4 so I can't do that, sadly. Ugh, not sure if this is worth it at all. Stay tuned!

...Edited to add...

My husband just told me that he needs Breathe Right nose strips. Sadly, they're not on sale nor is there a coupon, but...we need them. SO that makes things easier:

5 Oreos - $5
2 Buddies - $1.98
1 Smart Rinse - $3.49
1 Breathe Right - $12.99 I think
2 Dove body wash - $10.58 [OR the toothbrushes if they have them]

34.04 [30.45]

-5/30
-5 Oreos
-$1.98 Buddies
-$2 Dove [nothing if toothbrushes]
-$12 ECBs
-$8.06 on gift card [6.47]

Get back $3 Dove [or $6.99 toothbrushes] and $3.49 Smart Rinse

[The toothbrushes give back more $/lower OOP but are no fun!]
