While digging a bit more, I found a few sellers that have quite a lot to sell and for good prices with low shipping (as it goes through the marketplace with protection and they offer good shipping rates due to high volume) very easy to handle and I marked them as favourite because this is much easier to deal with than overseas, custom shit etc.
I'm definitely not at a point where I'd buy from Instagram myself, but I can see how people that have already built a relationship would. It's a bit similar to us here buying from other Hive members..
Thanks for your answer :) I live in Spain btw...
