Last night i purchased a Graco Ready2Grow stroller for $116. It Retails for $179 it was on sale for $144. and the cashier scanned the additional 20% off coupon to make the final price $116. The coupon didn't specifically say it was good on stoller's, car seats, swings, or chairs that is why YMMV. The coupon worked with out any hiccups or a manager override for my stoller purchase.
