It's easy for you to say "just order it and return" when you're from US.
I'm from Poland.
Schiit stack will cost me:
99$ for Magni Heresy
99$ for Modi 3
19.20$ sales tax for shipping that to my cousin in New York
18.39$ for FedEx Shipping to him
30$ for my cousing to ship it to Poland
266$ total already + there's a chance of another 23% of taxes once it's in Poland, so it's suddenly 327$. And i don't even now if i'd like it, and i can't return that in obviously. Also keep in mind that polish currency is... "schiit", and buying anyting in USD and EUR is not exactly that cheap for me as it is for you
Now, i can buy used/returned Sabaj D5 from Amazon.de for 369.99 EUR total, without anything more.
So if i think about that, it doesn't make much sense for me to buy Schiit stack unless my cousing can just take it with him and fly to Poland. And we all know that's not going to happen soon because of Covid-19
