In 1970 Silo made its first foray beyond the Philadelphia metro area, purchasing a number of Downing's stores from Sam Bloom in Denver, Colorado. Shortly after, Silo purchased three Appliance-TV City stores in Arizona from its founder, Jay Winslow. The Colorado and Arizona acquisitions enjoyed rapid expansion, as Silo applied its formula of low pricing, huge selection, and aggressive advertising. The 1970s Silo television jingle, "Silo is having a sale," was so pervasive that many Philadelphians today can still hum the jingle and would not believe that it has not aired in decades. Another of Silo's aggressive price promotions was a 1986 advertisement offering a stereo system for "299 bananas." Customers in Seattle and El Paso took the offer literally and came to the stores with real bananas. Silo honored the offer, trading 32 stereos in Seattle and three in El Paso for bananas; the stores lost $10,465 on these transactions.
