There is a monthly ECB deal where you can score Free AZO Itch Relief gel. Here is your deal:
Buy AZO Itch Relief $6.99
Get $5 ECB (Limit 5)
Use $2/1 AZO printable coupon
Free after coupon and ECBs
Remember, this is a monthly deal so you can do this throughout the month if you need a filler to use a $5 of $20/$25 coupon or just to use up your existing ECBs. And, the best kind of filler to use it one that produces an ECB.
