("After testing it in Seattle since 2007, Amazon brought the service to parts of Los Angeles in June * * * [Market researcher Sanford C] Bernstein also assumes Amazon will only offer the service in areas dense enough to keep the cost per delivery at or below $9. Indeed, delivery charges will prove a vital variable for Amazon. Perhaps that is why it is testing different models. In Seattle, it has no minimum order but charges delivery fees based on a sliding scale. In Los Angeles, customers have to pay an annual fee of $300, which includes the $79 fee for Amazon's Prime membership, which gives customers free two-day shipping on many items. With the fee, all grocery orders above $35 are delivered free")
