They're < $3 shipped on aliexpress. Shipping is slow, but that's cheap enough to just have a few on hand for when you need them.

About a year ago I looked into buying a large number of Wemos Minis and selling them on Amazon FBA, more as a capitalist experiment with my kids than to make real money. Turns out they're priced very close to optimal for selling there with minimal profit. In other words, you're paying for the convenience of Prime shipping, but nobody is making a killing off your $7 purchase.

I bought too many and thought the same thing.

Thought I could compete against all the nodeemcu boards.

Once I looked into amazon fullfillment, the margins went way out and I wouldn't make anything... And lose money if didn't sell quickly.

I just got an Arduino Mega beginner plus 37 sensor kit for xmas. I'm really excited to try out some of these different tiny SoC gadgets, especially looking at trying to build a basic hand-held tricorder since that has been an obsession of mine for a while. I also want to try out the mesh networking with either the ESP8266 or ESP32.

All my gifts were bought from Amazon, mostly for the speed of shipping and arrival. But I may just look closer at aliexpress or banggood to see what they have.

Thank you for sharing the link!

>Shipping is slow

I bought 30 latest revision d1 mini plus a few other shields, payed AliExpress premium express shipping.

The express shipping came out to 20$ (you can play with quantities to maximize items for bulk shipping price from same seller... Like remove one d1 mini to add 4 components to keep shipping price the same or add a few d1 mini till price changes and go back down 1 quantity, it's tiered.).

Item arrived to Canada within 10 days (came DHL).

This was back in November.

I get mine on banggood because they take paypal. Probably in between amazon and the other chinese web retailers in price.
