Aaron Groff & Son LLC has been selling specialty farm and home products since 1962. We’ve been selling Down-John for over 10 years, and we’ve seen spectacular results with this product. Currently Down-John is the only product for sale on our website, but if you have interest in other products, please contact us, and we would be happy to send you a free catalog.  We do not have a retail store or showroom. Our warehouse is located in Ephrata, PA; in the heart of Lancaster County. We ship UPS.
