we were checking on prices for 55 gallon drum man have they went up in price two years ago we were buying a drum of plastic for about $800 the other day we got quoted a price of over $1200 so I did get a gallon of plastic it cost $60 it has went up five dollars in one year so our hobby is getting more expensive all the time not to mention how much waste you will get out of the 1 gallon or 55 gallons so majoring is very important anymore we definitely have to major each Pyrex cup right to the nitty-gritty so we do not waste one drop.
