Canaan is competing with their distributors and Bitmain.They just dropped the price of the 841 down to $1625. Looks like you are right, the people rushing to buy earlier are going to end up paying more and getting it at the same time as the late buyers. If you're able to buy 20 from Canaan right now, you'll get them before the distributors. It's a 3 week wait for everyone else. Looks like Bitmain may drop their prices again too with this move by Canaan.
Canaan is not "competing" with their distributors. They work very closely with Blokforge and others to maintain their supply chain. They set up this distribution network to get Miners into the hands of the public without the ordering fiasco of 8000+ people all trying to order from their site within seconds of product availability.
Also as you can see if you read back through the pages Blokforge was able to work with Canaan to offer reduced pricing to customers through coupons and discounts as a good will gesture for purchases made during higher pricing a 4-8 weeks ago. That being said Nick and Blokforge have been very open about responding to email requests to try and sort out payment/pricing issues all you have to do is email them, and in my mind be curtious and reasonable in your expectations.
Also the 20 units you quoted, is still actually 60 MOQ from Canaan, if you try to order now it comes in with a set quantity of at least 3 packages.
