Cutting prices on notoriously expensive razors this year shouldn't come as a complete shock. 

Sales of men's disposable razors, a category dominated by Gillette, dropped 5.9% last year to $1.2 billion last year, according to Nielsen data. Men's electric shaver sales, where Braun is a major player, have fallen for over four straight years. Last year alone, says Nielsen, sales of electric shavers for guys dived 8.7% to $147 million.
