Yikes! I just went to create a shipping plan for a restock of my item. Amazon placement fees of nearly $154! I'm only shipping 2 boxes 12x12x8. Items are 9 x11 flat envelope sized. I know rates increase for 4th quarter, but at these increased rates and all the additional junk fees, I'd be losing money. It shows for an Amazon Optimized option, to send in 5 or more cartons. Would splitting these 2 boxes into at least 5 boxes actually make a difference in the shipment placement fees? Thanks!
