Diapers.com Gear products include more than 4333 items - from Britax, to Graco, and Fisher Price - we've got you covered. Check around! You'll see we've got great prices on all products. We deliver orders over $49 to your door for free in 1-2 days. Based on customer feedback, we have also expanded delivery to Alaska, Hawaii, U.S. Territories and APO/FPO addresses. However, due to the additional fees and challenges associated with shipping to these special destinations, we're asking you to help cover a portion of the shipping and handling costs. In many ways you could say our main product is customer support. It's what we work on the hardest.
