Britax, Graco, Fisher Price - we have them all! We work hard to make our prices as competitive as possible, and offer some of the lowest prices online. We do not yet offer guaranteed overnight shipping, although many areas of the country do receive their orders the next day. Note that some items, including those shipped directly from the manufacturer, will take longer to arrive; ship times for these products will be noted directly on the product detail page. Shopping online beats waiting in line any day. With Diapers.com, there are no trips to the store, no circling the aisles, and of course, no waiting in line. Ever.
