How long ago did you find the 100 Gillette Wilkinson Indian sword blades at that price?
Longer than 5 months but < 9 months probably. I recall seeing them last June or July for $6 when I was considering getting into DE wet shaving. When I finally made the jump in late October, early November prices on the GWS had climbed to $7.50 or so. Still cheap but not the irresistible bargain the Treet Platinum was so I bought the Treets instead. Now having tried both, I do prefer the Treet Platinum over the GWS, so it was serendipitous.
