$192.40 is the current item price before applicable tax, shipping, local delivery, pickup handling, or installation labor. The Merchant shipping table currently treats this A20 as a 10 lb shipped item in the high-end septic-parts class, and BE Ohio confirms the final fulfillment path before release.

Do not order an A20 as a generic aerator replacement. The A20 supports post-aeration in specific NPDES treatment trains and must be verified before release.
