>As far as I can tell, Adafruit doesn't price gouge.

They charge ridiculous prices for LED strips, the same strips you can get anywhere.

Here's one example:

https://www.adafruit.com/product/1461

Black LED strip. 60 LEDs/meter.

1 Meter = $24.95

4 Meters = $99.80

And they advertise 4 meters as a "full reel" when everywhere else 5 meters is considered a full reel. What jerks!

Same exact thing, except 5 Meters, $22.99:

https://www.amazon.com/LOAMLIN-WS2812B-Individually-Addressa...

So, let's calculate this price gouge.

Adafruit price per meter at 4 meters/roll = $24.95

LOAMLIN price per meter at 5 meters/roll = $4.60

Adafruit is charging 5.42 times the price.

And if I want to wait a few days more to get it delivered, Aliexpress has the same thing for $11.26 per 5 meter roll!

Every LED Adafruit sells comes from China, they do not make their own LEDs. They just mark up the price to a ridiculous extent and they prey on well meaning but clueless electronics hobbyists. There are many other examples, but I think I've spent enough time on this topic.
