I put in a supervent chimney in January and it has been great. I went with 8 and had to use 4 sections @ $95 a section bought at medards and had a local contractor install it for $200 cash. It ended up being under $800 with installation after buying the sections and the other connectors and black pipe.
The United States of America and its agencies and instrumentalities (also referred to as United States governmental entities) are also exempt from paying New York State sales tax on their purchases. Other states of the United States and their agencies and political subdivisions do not qualify for sales tax exemption.
A sales tax is a tax paid to a governing body for the sales of certain goods and services. Usually laws allow the seller to collect funds for the tax from the consumer at the point of purchase. When a tax on goods or services is paid to a governing body directly by a consumer, it is usually called a use tax. Often laws provide for the exemption of certain goods or services from sales and use tax.
