Hills k/d prescription

Does anyone here buy renal food regularly?  A friend of mine lives oversea, and she asked me to buy hills kd for her from National pet pharmacy, but my cats don't have renal problem, so I was wondering if anyone can lend me the prescription.  The website asked for pet name and vet.  

Or does anyone know where I can buy it without prescription?

You have to have a prescription for it.  If your friend wants you to buy it, she probably has a prescription, doesn't she.  It's just that they won't ship it to her overseas?  Was that your plan, to have it shipped to you, then you're going to ship it to her?  Surely there are kidney foods that can be purchased/sent to Europe, are there not?  Royal Canin makes a kidney diet that can be purchased in the UK. 

I'm probably getting in too deep, but don't know if anyone will be able to assist you or not, so am giving you other options.
