A Raspberry Pi costs about R$200 in Brazil, or US$60.
And the majority of these consoles are bought by poor people (income of equal or less than a minimum wage in Brazil, that is R$788 or about US$235), that in the majority of cases don't have too many familiarity with technology.
So imagine that you have a low income like I said above, you have a teenage child that wants to play games. You probably don't even know that Raspberry Pi exists, so you go to a local store and see these kind of video-games selling, that are much less expensive than current-gen consoles. To make your kid happy, you buy this old console, so this is why there is still a market for them.
If I remember right you can't buy a Raspberry Pi from the traditional online stores that sell them (they don't send to Brazil), so you need to buy from a reseller. I ordered a Raspberry Pi online from eBay, had to pay US$50,00 that wasn't exactly so bad (and it was a kit instead of only the RPi, including memory heatsinks, USB charger and a case). So yeah, it is possible to save a bit of money, yeah.
However, this is counting that you don't pay the abusive taxes that the brazillian government asks for imported goods. If I had to pay those taxes for my RPi I would pay 60% of the price of the product in taxes, more 12% for IOF.
I didn't buy CHIP because I would need to pay US$15 for the delivery cost.
Makes sense if you know how to configure one, but not everyone knows technology very well, and this is especially true with poor people. This kind of console is popular to this public.
