Surprised to not see this one listed here already.
I have been a customer of Mueller's since 1991.
They always have the lowest priced flights and stems if you buy in bulk.
Realized I was running low on stems today so I put in an order for 20 sets.
Cost me .34 cents each for medium nylon's.
Got talking with the customer service rep and told him about me being with them since 1991.
He was very thankful and gave me free shipping today.
For the guys in the USA, if you haven't used Mueller's.... you should.
Great company.
+1's all across the board for me.
