You all remembered to grab your $5.00/$25.00 coupon from your e-mail today right? Good!
Here's a deal scenario for you:
5 Revlon Nail Polishes - on sale for $4.99 each ($24.95)
1 small filler (to get to the $25)
Use 5 $1.00/1 Revlon Nail Polish Q's (4/10/11 SmartSource)
Use $5.00/$25.00 Purchase
Get $20.00 ECB's back
Total OOP $15 (ish - depending on your filler item)
Money Maker of $5.00
Technically you can earn up to 6 ECB's of $4.00 each with the Revlon - so if you don't want to do the filler and 5 polishes you can grab 6 - Total OOP is $18.94 - you get $24.00 ECB's back - Money Maker of $5.06.
