Some of these Amazon deals may have longevity but most are going to be strictly “while supplies last”, so don’t dilly-dally if you find a great price on something you really need or just seriously want.  I’ve only listed items with FREE SHIP and in most cases FREE RETURNS just in case it doesn’t work out.  Here at CarseatBlog.com we always recommend that you “try before you buy” but we understand that’s just not possible in many situations. Free shipping with free returns, in case it doesn’t pan out for whatever reason, is the next best thing!
