FedEx's announced rate increase for 2017 was 4.9%. My most commonly used box is a 31x3x18" box for a newspaper frame. It weighs in at 6 pounds. I started having these boxes made last year after FedEx switched from weight pricing to Dimensional Weight pricing . The box I used before that was a uline 28x4x24 box; If I were still using that box, it would now cost $28.33 to CA. When it was weight based pricing it was around $17.00. Prior to the first it cost me $17.69 to send it from PA to CA. As of January first, the cost for the same package is now $21.70, a 23% increase. That's still cheaper than USPS but not much. If there is a DAS, then USPS is cheaper. Why does it cost $4.01 more to send this when the announced rate increase is only 4.9%? Because they changed the formula for dimensional weight. Prior to 1/1 the formula was L x W x H / 166. Now it is L x W x H / 139 Changing the DW formula resulted in my package going from a dimensional weight of 11 pounds to 13 pounds. For most shipments east and some west of the Mississippi, it is now several smackeroos cheaper to ship that package via USPS rather than FedEx. My postman is going to be a lot busier. This morning he picked up 21 packages. At least half of them would have shipped via FedEx prior to 1/1. I know most of you don't ship a lot, but if you do, be prepared for sticker shock.
