For people who are considering “taking delivery and selling their phone” or “selling your order via Purism support changing buyer details”, it appears that this route will be difficult due to lack of demand.
Witness the difficulty here: [ASIA] Librem 5 for sale - #12 by irvinewade where they are trying to sell a Librem 5 (with Asian version of the modem) for $450 (or $520 on ebay).
[Edit: Here is one on offer from Europe. [SALE] Librem 5 Evergreen Europe unopened . Ask is 900Euro (to cover import duties) while the most recent Bid is 500Euro+ up to 150Euro if the buyer has to pay import duties for a private transaction.]
