That's a tough question. The answer will depend on where you buy the fans and what type of fans you want. I know of one reputable online seller that will sell you a trio of Honeywell fans for about $130.00. The price really depends on what models you wish to own.
well it depend on what fan you want then the table fan should cost ten dollars and the bigger fan cost 65 dollars the also have the fan with three heads that can turn three different ways for wour room can have an breeze all over the room and the prices are resonable
