Essentially the only reason is for modern Android, but its not as though any of these Android phones (except the Nokia) will ever see multiple years of software updates.
Brick and mortar only though, and stock varies. I usually power dial all the local stores, then go to the ones with the most stock and clean 'em out. Easy way to get a few dozen Androids in short order.
Sadly, at the $5 price point Amazon and eBay will never beat Brick & Mortar stores, as shipping is more than half the cost.

Depending on your country, you may have to pay import charges if you buy direct from China or Hong Kong. Even with import charges, Xiaomi phones still usually work out to be a good deal. Warranty coverage is limited if you're outside of Xiaomi's core markets, but parts are cheap and readily available if you need to replace a cracked screen or a weak battery.
I wouldn't recommend other Chinese brands like Doogee, Leagoo or UMI. The hardware is usually good, but the software is often poor and you can forget about updates.
Those names sound like Dodgy and Leakgoo, easy to remember, don't get those. Thanks.
The Samsung 2017 A3 is what I wish I could get but thanks to pointless market segmentation, the only variant that works well in North America is impossible to buy and it's now being obsoleted by a replacement with a 5" screen.

For people who just like their Android flavour, they also provide ROMs for other devices: http://en.miui.com/getrom.php?m=yes&mobile=2 Presumably the same suspicion of Chinese goods coming packaged with spyware would apply to those images too I guess.
They make all of the phones, actually. You have to pay hella licensing to get a cell chip that works in the west. Then, they sell that phone to the company wholesale. Then the American company upcharges for retail.
You can get a Samsung S whatever for 1/3 the price if you don't want to connect to a cell network and don't mind waiting 3 months for it to ship.
