1. I did not notice the M1 was being offered on rent. I assumed it was for sale at the listed price.
2. Since 58.31 € is an unrealistic price for an M1 machine (and since this is a European site) I concluded the site must be using a comma instead of a dot. 5831 € is a realistic price for a Mac afterall.
Unfortunately the site is using a dot for a dot despite being European and the M1 is being offered on rent.
