quick trip to wags for Swiffer

Got a pretty good deal On these Swiffer Wet Jet Refills On sale for $3.74 each when you spend $10 you get 3 back.
So here's my deal
4 swiffer refills= 14.96
Used two Bogo coupons from 2/27 P&g -7.48
Used 2 $3 RR from Motrin deal last week -$6
So $1.48 oop and got back $3 in RR's!
