April coupon challenge part 2

I had planned out this shopping trip and

 even though I've been using coupons for more than 30 years and was shopping alone with no distractions, 

 I still made 2 goofs.  

CVS

The CVS coupon scanner printed another Clear hair product so I got a 2nd one free.  The Suave deoderants were 10/$10 with a $3 ECB after purchase.  

I used a $4 ECB and a few Suave coupons but my first goof was not having a $2.50 ECB that I earned previously with my list.  I spent $6.82- but it would of been $2.50 less.......

Walmart 

Can you spot my 2nd couponing goof?  I had 5 Maruchan coupons but the 5th one was not accepted at the register as I had only picked up 4 Maruchan and 1 ChowMein noodle bowls.
Saved $12.50 with coupons.

so far,  I've spent $18.88,

got 28 products 

Sales tax so far is $3.80 - because nothing in Oklahoma is really free,  except maybe the wind
