Why was NR Mags silly enough to sell the AA Mags at only $100 a pop to have someone else scalp them at higher prices (gonna pay to play).
Suppliers / ticket sellers love scalpers ( I worked with a ticket selling agency a few years ago ). The scalper buys up a block, lowering the cost of sale per ticket, and then takes on all the risk of moving them. Remember what happened to the Magpul scalpers a few years ago when supply picked up? They lost a chunk of money.
Also, the reputational issues: the supplier sells at a normal markup, making what they expect (only more quickly because the scalper hoovers things up), and the scalper then takes the reputational hit for above-list pricing. When Harley could not meet demand, their dealers jacked the price up, so Harley did not worry about reputation - the dealers did.
Scalpers have a valuable place in the economic system. Either a scarce+in-demand good / service is priced so that regular people can't afford it (front-row seats! Kel-Tec KSGs!), or everyone enters a lottery and waits an indeterminate length of time. At least using pricing as a response to scarcity, a regular person can decide to treat themselves to something special - with a lottery, you take your chances regardless of desire or ability to pay.
An individual - "scalper" or no - who owns something that has high street value is a fool to sell it for less just for the dubious pleasure of "helping the community". You might sell it for a bit less to a friend, but not an internet stranger.
So... having said all of that, I will sign-up for a few mags when they are available for pre-order. I might also get a .50 Beowulf upper to match.
