Bottom line, never, ever and I repeat ever, let your order processing task fall behind 1 day or 2 days at most, this is extremely detrimental to your business in the long run. It will lower your ranking, give your customer a bad experience, result in negative feedback, lower your over all rank and worse, restrictions get applied to your accounts selling limits. Every day counts here when it comes to processing orders as we do not have any control over the shipment, the sooner it is processed the more likely it will ship out from the source and arrive to your customer.
