Totsy currently has some awesome deals on Timi & Leslie Diaper Bag/ Stroller combinations. I have never seen a diaper bag that matches the Stroller. But the combination is only $149.99, which is a great price for the stroller alone.
They also are currently offering some great deals on winter wear and Juno Baby.
As an FYI, this daily deal website takes a LONG time to ship. Usually, around a month, however I have ordered from them before and the items were great.
