Great news for eBay sellers: FedEx One Rate means more ways to save on shipping. You can now print FedEx One Rate labels right from the eBay label platform and can get a simple, predictable, flat rate shipping option for your express packages.
With FedEx One Rate you can add to the box without adding to the price. This means sellers no longer need to weigh or measure express packages under 50 lbs.
Ship up to 50 lbs. in FedEx One Rate paks, boxes, and tubes
Ship up to 10 lbs. in FedEx One Rate Envelopes
12 different packaging options
Up to 45,000 drop-off locations
FedEx One Rate pricing is available for these FedEx Express services:
Standard Overnight and Priority Overnight One Rate
2-Day and Express Saver One Rate
In order to use FedEx One Rate, you must package your items using the One Rate packaging options (Envelope, Pak, Small Box, Medium Box, Large Box, Extra Large Box, Tube).
This could save us some money with the Small Box as the dimensions are quite large. I do not know if there are any eBay discounts but, if there are, this update brings the cost down below USPS for a variety of items, particularly bulk and used sets (and heavy dolls or cosmetics?).
