Is a nice initiative and that's definitely how sme big brands are built by coming up to be pioneers to what could be a trend I the near future. In that, you create a pilot study for others to follow and possibly have some tips that never comes out as a business strategy on how to keep up with the management.
On what I would have liked to buy?Pretty much everything or or things that isnt groceries (at least not at the moment), especially the heavy duty stuff and most of all, electronics. Sadly, when it comes to cryptos and transacting across borders as per shipment, it comes with some challenges as you've already sited
As for overseas shipments, not at the moment, but primarily because of logistical reasons. We want timely deliveries, so we only accept deliveries within Australia for now (it makes it easier to manage for the time being). What country are you from by the way?
And there is always an issue of trust/insurance. Little wonder why we've got escrows these days to mediate between parties.
