When they first expanded beyond the NYC metro area, I could only find Rao's in Wegman's. Now, they seem to be in every grocery store.

That said, years ago, I stumbled onto 10-15 jars of it at a sale our local natural foods warehouse hosts to benefit Relay for Life. They take customer returns (i.e., a case was damaged during shipment, so the customer returned it, and 11 of the 12 jars were not damaged) and sell them at incredibly low price points. The "damaged" goods are accumulated throughout the year and they usually host two or three sales each year. One year, I was able to snag several jars of Rao's sauces for between $0.50-$2/jar. Other great finds included packages of Biscoff cookies (those that sell for $2.50/package at Target and Walmart), for $0.50/package, 20 lb. bags of premium dog food for $10/bag, and cases of DaVinci penne for between $1-$6/case, depending on what time it was. It started out at $6/case, but as the day and sale progressed, they eventually dropped the price to $1/case. I bought one case at $6, and then bought another 3 or 4 cases at $1/case.
