Pete,
A gallon of water/milk here states it is 3.78 liters(litres)
Either way .... a few GREEDY SOB's with enough money to buy ANYTHING are making more than their share by charging more for a product that cost no more to produce than it did 10 years ago!
BUT WAIT!!!!!! If we drill in ANWAR for oil that needs 4x the refining of gulf oil .... prices will then again INCREASE , while we DEVISTATE the largest pristine area ON EARTH!!!
Maybe GW's war on oil(terror) can solve this ;)
