Re: Unacceptable
Disabling the equipment is only a condition of the discount. If you want to keep yours, simply pay full price.
Exactly! More companies should do this. M&S could get you to shred your old clothes for a £5 discount, Volkswagen could give you cash-back for drilling holes in your engine block. Persimmon could give you 30% off for burning down your old house. I can't see any flaws whatsoever in this practice, all that matters is there isn't a law against it. (Unless you live in a terrace I suppose.)
