I realize we have a buyer intel section but I thought this applied here. Please move if I was wrong.
Went by Costco (W Quincy) today and they had Ball canning jars for $5.99/dz for pints, $6.99/dz. Both regular mouth. That's a pretty darn good deal. If you want some act fast because it appeared they won't be restocking the pints. (BTW You can always tell if they will not restock immediately because they put a little * in the upper right corner of the price sign.)
