$100 for a RGB Led strip light, when the Amazon price is ~$30 with an
infrared controller.
One of those places. The costs are high, but they may make it simpler for
you to buy a single item, or collect together things of a similar nature
that would otherwise cause you to shop at multiple outlets.
Even Edmund Scientific forty years ago was like that. IN some areas the
prices were great, some other thing weren't, but if you were building a
science project, it meant you could get everything from one place.
I once sent away for a catalog aimed at "audio snobs", thinking it might
be a source of parts. It wasn't, because they sold only high end
capacitors and the like (for that maximum high fidelity sound) and each
cost an arm and a leg. But you could buy in single quantities.
