Yes, but it's almost 3/4 the price of a gallon, for 1/4 the quantity. Look on REI, it's $15/quart (MSR) vs $19 for a gallon (Coleman). A quart of Coleman is $12 on amazon.

Many places have stopped carrying white gas, I don't know why, whether reduced demand or higher transport costs due to it being hazmat.

I loved having a gallon around, served many purposes; Stove fuel, thinning varnish (very similar to Varnish Makers & Painters (VM&P) naphtha), cleaning a spot on a necktie (my dad used to use gasoline and the tie smelled of it forever, white gas evaporates with no residue), petrol ("Zippo") lighter fluid at vastly lower cost, de-stickier.
