Gasoline service stations stopped offering them due to the energy crisis that occurred and many supermarkets started spending more money to advertise lower prices rather than issue stamps.[12][1][2][13] During the 1980s there was a brief resurgence in the popularity of trading stamps, but overall their use continued to decline.[14][15] Their role has been replaced by coupons, rewards programs offered by credit card companies and other loyalty programs such as grocery "Preferred Customer" cards.[16] Through the 1990s and early 2000s the majority of the remaining trading stamp companies either ceased operations or converted to an online format.[7][17] In 2008 the last operating trading stamp company in the United States, Eagle Stamps, closed.[18]
