I wanted to double-check to be absolutely sure, but I didn't see anything on USPS' page about the Ground Advantage service that references dimensional weight being a thing for this class of mail. Is that true? Because if so, it means I can list a whole bunch of things that I'd been holding off on listing before due to the dimensional weight requirements of Priority Mail. (I didn't want to use UPS or FedEx given the hassles I've heard of with them upping the price for the shipping after the fact with larger packages...)
Ground Advantage is subject to dimensional weight, including GA under 1lb. First Class Package wasn't subject to dimensional weight, but now its replacement GA is, regardless of weight.
Today, only Media Mail isn't subject to dimensional weight.
As noted in the other posts, Ground Advantage does use dimensional weight. Media Mail doesn't.
You can see an explanation of dimensional weight in footnote 4 on the page with Ground Advantage fees in Notice 123, and it mentions the specific secton of the DMM that includes the formula.
