The price of Chinese made sap sack holders and taps have increased 30 percent this year because of tariffs coming into the US.
The Sap sack holders are now $3.85, 5/16″ aluminum taps are $1.85 and bags are $0.30 each or .25 if you buy 250 of them. Another option would be to purchase my used 4 gallon galvanized or 3 gallon Aluminum buckets with a new 5/16 plastic bucket tap and lid. The bucket, lid and tap setup would cost $7.00 vrs $6.00 for the sap sack holder, tap, and bag.
I know it $1.00 more for the bucket set up, but I have never seen a squirrel or chipmunk chew through a galvanized or aluminum bucket or seen wind or ice break a bucket. Anyway its something to consider when you are thinking of adding more taps. Buckets do need to be rinsed out every year which is a down side, however you will not have to buy bags every year and you will keep the plastic out of the land fills.
