Answer by Kynan Eng, brain-related research and commercialization at universities and startups:

It would cost about \$12.86 billion to buy one of everything on Amazon. I calculated this value as follows:

• According to this link, the main Amazon website offered 488 million items in 2015. Of these, an estimated 479 million are available.
• I estimate the average price of an item on Amazon is \$26.86, with an uncertainty (standard error of the mean) of \$6.03.

To estimate the average price of all Amazon items, I followed this procedure:

1. Click on Random Amazon Product. As the domain name implies, this site gives you a link to a random Amazon product. No, I don't know why this site exists either.
2. Discard the product if it is free or not available, but keep count of it.
3. If more than one price is available, select the product price highlighted in red (this is the one that Amazon probably wants you to buy). If that is not available, select the first price listed looking from top to bottom, then from left to right.
4. Repeat until 100 nonzero items are collected. Yes, I really wasted my time doing this. I thought about trying to crowdsource this data collection, or writing a bot to do it, but that would have been more work.
