I think you got a great deal! I can't wait to see them all hooked up.They sell for $200 each retail, but were on sale for $79 each, "cash & carry". The barrels were available without hardware for $32. Yes, I could have made them for less than $79, and I would have gone DIY if the barrels weren't on sale.
We did this a couple months ago. Hopefully won't have to do that again until we're ancient.Roofers are coming on Friday

. You may be able to see a little reminisce of it.
