Around 40 Otoko no Isekai Tsuuhan

Isekai anime where a dude is isekai'd and has the ability to do net shopping directly from Japan and obtain items from there too. Main difference would be that the net shopping abilities are part of the plot differently to each other, Tonsuki using it mainly for gourmet purposes introducing yummy foods to characters whereas Arafoo using it mainly as a ways of making money purchasing things and crafting things for residents. 

Similar concept, but the MC has the power to hop between worlds. She buys things in the new era, and sells them in the other world, which is much older. Has access to anything from the new world as well.
