Would you be able to buy a couch on Amazon? The #1 bestseller on Amazon currently says "Currently unavailable. We don't know when or if this item will be back in stock." so it doesn't work here the same way other retailers don't work.
So you're saying you can't get a passport from the government but you're able to buy certain things on Amazon therefore Amazon is better?
It is virtually impossible to get an appointment at the passport office in the US right now. Not a local passport office, ANY passport office. There were people outside the one I went to offering a Nintendo Switch to people to trade for a time slot. The shortest wait time I had on the phone was three hours, and I called one minute after they opened.
And if you have only a single citizenship, being stuck with the passport office is about as stuck as you can be.
It works... ok. The delivery company only delivered one of three boxes for my bedframe, I got a refund but now I have a headboard and a mattress on the floor, and the model is out of stock. Woe is me, right?
Everything else has gone off without a hitch, and so, tl;dr yes you can buy a couch on Amazon. Or Wayfair. But not necessarily at Ikea, at the moment. At least not here.
I recall an article talking about how manufacturers with limited stocks would supply Amazon first, prioritising Amazon other channels, due to the incentives of their contracts and the penalties imposed by Amazon's business processes. Unfortunately I can't find the article now...
