Are You Gellin'?

Thank you Dr Scholl's and Walgreens!
If you don't know Dr Scholl's are on sale all month at Walgreen's 2 for $20 with $10 RR wyb 2
Dr Scholl's had $10 coupons in the 4/26 insert. (We received the $2 so I bought mine online)

I did separate transaction of 2 at a time.
2 for $20
2 $10 off
Total $1.35 tax
Received $10 RR

What did we buy with some of our RR?
