You do realize that this model is basically the one used by companies who make printers, right? The printers themselves are sold pretty cheap and the price of ink is gouged up. The only difference is precisely how little the razors are "given away" for.
Printers aren’t “given away” either, at least not at any stores I’ve ever been in. If you have evidence of any printers being given away for free then link them, otherwise admit you’re making a false claim.
