Have you tried Aliexpress?

From what I've seen, that is the option which saves the most on shipping. Anbernic's own site adds way too much with shipping, but when they sell on Aliexpress that drops so significantly. I've seen a few users saying it is the way to go, so maybe it is worth a look!

(And I totally understand, with those handhelds the power to run GBA games is well in hand, but the form factor of this RGSP is a beautiful nod to the original!)
