I've heard of consignment shops doing this, not big stores! Schweeeet!!
Babies R Us is having a spectacular "Fill a Bag" Sale. You'll receive this cute shopping tote to keep, then all clothing and shoes you put inside (excluding clothing above size 4T) is an extra 25% off! Use this coupon to shop now through 4/22!
Thanks, The Mommy Trade and moneysavingmadness
