Got mine off of e-bay a couple of years ago. At the time, it cost $45.00, but I had to pick it up ( in Il). Otherwise the shipping charges would have been $40.00 more.
$11.99 to $13.00 shipping for the few 55 gallon drums I checked.. I buy from these guys fairly often, great service and extremely fast shipping. They are located in Ohio..
Search the Louisville craig's list. There was a guy down there that had tons of different containers( buckets, barrels all kindsa stuff.
I don't know where you are but the Rural King in Columbus sells 55 gallon, clean, blue barrels for $12.Or they did a few months ago anyway. Check any tractor supply or rural king near you.
RK's barrels used to hold anti freeze... I bought one to use to catch rain water and then got this little tidbit of info. We were gonna collect the water from the chicken coop in the barrel to water the chickens, we are still looking for a barrel to do this with.
