I think pigsy's referring to shaving related 'stuff'... right?
Non original mach-3 blades on allegro. 36pln for 12 = 3pln per blade inc shipping
Original mach-3 blades on allegro. 27.95 for 8 = 3.49pln per blade inc shopping.
Two ways to look at this.
1) 3.49pln (1usd) for an original mach-3 blade is pretty dam cheap and renders buying the non-original version, pointless
2) It works out at 2.10pln per blade with the dollar shave club inc. shipping and you don't have to remember to order blades again. Cheaper and saving you time is pretty important. With that in mind, I'd imagine you could justify higher prices than the cheapest allegro seller.
Just a bit of fun... procrastinating really.
