In May 1, 2013, I got my Gillette TTO, http://theshaveden.com/forums/threads/what-gillette-razor-do-i-have-here.33042/ I used to shave with a Mach3 system, going through about four blades a month (would usually change out Mondays for the week). A 12 pack is $31 http://www.walmart.ca/en/ip/gillette-mach3-razor-blades/6000053639341 or $2.58 a blade. In the 37 months I've used my TTO I would have used 148 blades x $2.58 = $382. I buy Personna Blues https://www.amazon.ca/PERSONNA-Blades-60-0257-Double-100-Pack/dp/B0077LAJT2 with free shipping (I buy x2) at a cost of $0.20 a blade. I still like a new blade every Monday, so that's $0.20 x 148 blades = $30.00. So, just in blades I've saved $352! Since switching from squeeze cream to D.R. Harris soap (in cool mahogany dish) I'm also saving. I go through a puck every six months, at $22 each, so that's about $50 in pucks over 37 months. I was buying a tube of the Real Shaving Co. cream once a month for about $7.00 a tube, or $259 over 37 months. So, in soap I've saved $209! So, just by making this simple switch back in May 2013 I have saved over $561.
