Almost all made-in-China consumer electronics are cheaper in the USA. I'll have visiting friends bring me new cameras, phones, etc. rather than buy locally in Chengdu. Makes for a very circuitous route for these items.
Really? Spam? I kind of doubt it, unless everyone was buying penny stocks, loan refinances, and tummy tuck devices. My two Cyber Monday purchases were both driven by email marketing, but neither one was "spam".
Beacause I don't relish the thought of shelling out over $900 (unlocked iPhone 6, 128 GB, $850 + 8% tax) any sooner than I have to. Even if I got one subsidized, it would still be about $500. This isn't pocket change.
