Say a Fusion blade a week, $3, so that's $1.50 more than I paid when I had my dying mop, and a bottle of Headslick, $7-8, lasts two months or more, some Nivea balm--$5 or so, lasts 2-3 months, and some benzoyl peroxide 10% gel--$2.50 for 2 months. I'm beating the price of haircuts by at least 100%.
Cost item, I picked up some Gillette Express flex blade disposables at WalMart this morning--over $6 for 4, not cheap, but worth a try--Noodles gave them high marks.
