Mmm, beeeer!
Seems we are three already.
I am in with 2 boxes. That's 30€ here.

Btw. Thinking future proof. How much is a used Xperia 10II in your area?
Bundyo just snatched one for 150€ in Bulgaria pick up locally from a private seller. When i look into german refurbished prices its more like 250€.
Thinking low end, refurbished Xperia X go by 100€ even here.
Another option would be someone graciously donating an X/XA2 but there's the shipping cost at least.

But the more important question is, do you even want to continue? Don't want to nudge you or something
