Hey Bro,
I don't think you should be apologizing for anything. You run your business the way you want to, you sell to who you want to. A lot of makers have a VIP list of clients that help them when they started out and they give them priority. Last I check, that was a good thing and this is America.
Do people get butthurt? hell yes, but just move on. I've missed out on really expensive knives that other "insider customers" got, it didn't offend me, it's a part of business. I'm not saying you have an insider group or not, it doesn't matter, it's your business.
I also have multiple degrees and a graduate degree (MBA), that still doesn't qualify me to tell you how to run your specific business. One of the first things you learn in business school is that businesses are unique and require in-depth knowledge to effectively run them. Having an advanced degree means you should know better than send unsolicited business advice, which by the way is not advisable for legal ramifications. You put yourself in a legal situation where you can be liable for giving bad advice. Having an advance degree also doesn't give you the right to be an opinionated ahole to everyone about their business.
Run what you want bro, keep posting sneak peeks, it's your advertising forum.
