Ground Advantage pricing quirks?
I'm noticing from my own shipping for things on ebay and in a post in Instagram - recent changes in USPS rates (at least for commercial rates for ground advantage) have quirks.
I've seen a couple times when a package that weighs just under 2 pounds costs more to ship with Ground Advantage than the same package weighing 2 pounds.
And I saw an instagram post where someone said they are including 'free' rocks in their shipments to lower the costs.
It doesn't seem to be the case in all situations. Anyone know where I can see the commercial ground advantage rates? When I google, I only find the retail ground advantage rates.
Anyone else notice this also? Know more about the nuances and how to benefit from them?
