I believe most of the rationale was not wanting upset customers annoyed with getting different prices than others first and foremost, but also technically pricing system is already extremely complex and dynamic per user would add an order of magnitude to scaling challenges and viewed as not worth it.. Business pricing itself required many changes to internal system.

I know of some people who do this. Basically, list tons of items on Amazon from local speciality stores, Costco, etc. They markup prices, of course. Then once a day, on their way back home, they pickup stuff that was bought, pack it at night, and then ship it in the morning. You are basically paying for someone else to shop.

I was introduced to this side-hustle by my friend and did this for a few months, but it was too much of hassle for very little return. Very hard to scale.

For example, the range for my preferred elderberry syrup is from $20 to $45.

I waited the price to drop back down and then restocked.

YMMV

>Although some preliminary research indicates that elderberry may relieve flu symptoms, the evidence is not strong enough to support its use for this purpose.

You may want to find a new doctor.

There seem to be some conclusive studies on elderberry helping for influenza.

Ex: "In conclusion, the proprietary elderberry extract used here is effective in controlling influenza symptoms and is complementary to current anti‐viral agents. The safety and ease of administration warrant further investigation of its clinical efficacy in children, elderly and other high‐risk patients of the proprietary elderberry extracts." - http://www.omicron-pharma.com/pdfs/ElderberryClinicalOJPK_Pu...

Don't ever tell a patient to disregard personal experience. Someone who has suffered a chronic condition, and learned enough about it and her body to find an effective non-pharmacological treatment for it, knows more than a room full of physicians about how that condition is best treated in her body. Besides, don't we know by now that most studies (especially non-replicated ones on unpopular subjects) are worthless?

I'm sorry but this is terrible advice, and is precisely how people like Steve Jobs die for no reason.

I wasn't.

> Finding some half-assed study that might apply is no excuse.

You're clearly not worth arguing with if you can't even be bothered to read the things you're commenting on. The only thing half-assed here are your arguments.

But sure, tell a patient to find a new doctor, when you know absolutely nothing about the situation. If I seem somewhat inflexible on this issue, it's because I (and friends of mine) have been pressured to avoid nonpharmaceutical treatments that experience has shown to be effective. On this topic I am not indifferent.

The trouble with facts is they keep changing.

It takes a lot time for the latest clinical results to become mainstream. My doctor is OCD about staying current. Think Dr Rhonda Patrick meets Dr Terry Wahls meets Tim Ferriss meets Dr Atul Gawanda.

I'm still alive because of research, experimental treatments (seattlecca.org, fredhutch.org). I try a lot of things that others shouldn't. With mixed results.

The upside is future patients benefit from my experiences.

Thanks for the link. I'll consult my doctor.
