Should I carry more products at my clinic?

I've always been wary of healthcare practitioners who want to sell you a ton of supplements. It seems really easy to slip into an ethical gray area (prescribing something you're making a profit on). That said, I have slowly accumulated a few special products that I handle as a service for my patients. These are things that are not easily purchased (Anti-Inflammatory Pancake Spray, Correct Toes), or I can offer them cheaper (Sea Bands) by buying in bulk. I am considering carrying a few more things and I'd like your opinion. Please be honest - I will be getting your responses anonymously.
