Extreme Blade Price?!?!!??

[grasssin]

Bought my first Extreme blades today, total cost for each blade...............$16.65?!!!??! WOW..... guy at the desk tried to reassure my by telling me "they last alot longer than regular blades so dont worry about it"

Is that a reasonable price for these? Tell me he is right and my ONLY dealer in town is not ripping me off.....
