One of Amazon’s newer initiatives, Seller Fulfilled Prime, allows sellers to qualify for Prime without using FBA or Vendor Central. Amazon’s metrics for this program can be difficult to meet, but that’s where our 30+ years of fulfillment experience add so much value. Same-day shipping and discounted ground & 2-day shipping rates allow our customers to exceed Amazon’s requirements while still maintaining the profit margins needed for it to make financial sense without FBA. Our transit-time based rate shopping selects the cheapest option for carrier guaranteed 2 day delivery, so if not purchasing shipping through Amazon's BuyShipping API the delivery metric can still always be met while minimizing shipping expense. We are also located in northern NJ, right in the middle of the densely populated northeastern US, so a substantial percentage of orders can deliver in 2 days via ground service.
