White gas is "straight run" gasoline - no additives - not readily
available today.

Hidden as camp fuel at Walmart.

Speaking of which, it tends to sell in the gallon cans there at about twice
the unleaded filling station gallon price. So this should be around $3
something again. The local Walmart has had neither Coleman brand or the
store brand for weeks, and the shelf tag still has it at almost 9
dollars/gallon from last summer (when gasoline was 4.50/gallon). There is
one badly dented up can that has been sitting there for months unsold.

Sure looks like the oil price has put the supply of this item into turmoil.
