As someone living (near) Seattle, this is a major issue for me every product launch and I don't have a solution.
The area's geography just isn't conducive to allowing a single brick and mortar store to survive and compete with online retail for costs vs volume; but without a B&M store there's no good way to do physical presence anti-scalper tactics.
I can't even get in a purchase opportunity lottery since AMD / Nvidia don't do that sort of thing for allocating restock quota tickets that could be used as tokens to restock product if a purchase is to the correct shipping address.
