I recently bought a "gallon" of paint at Sherwin Williams in that new
plastic jug with a handle and a pour spout. When I got home, I was
outraged to see that the container is labeled as having 123oz (I think)
or "3 27/32" quarts (I'm sure). What a rip off!! I expected I was
buying a *gallon* of paint and they preyed on me because of that
reasonable expectation. ...snip rest of diatribe...

Well, you'll be pleased to learn this is as it has always been w/ base
for tint--there's room left to make the full gallon w/ the tint.

To be sure, I just checked on several really, really old (some as much
as approaching 25-30 yrs) from several manufacturers including S-W.
All tint bases were from 126 to 128 oz. A couple of cans of finish
exterior white which were not a tint base were full gallons. One of
those was also S-W, btw...
