70 USD more for an ERA compared to a Libra 2 is a lot.
In Germany the prize for the Libra 2 goes from 170 to 190 EUR, the Pocketbook Era will cost 199 EUR, that is a difference of 9 - 29 EUR.
Pocketbook will sell the Era together with a cover for just one additional EUR. I can also get a 10 % discount, so buying the bundle for 180 EUR incl. shipping is a no-brainer for me.
The Sage is too big for my daily commute, I also don't need the extra functionality. It also is quite expensive in Germany (366,97 EUR for the Sage + Stylus + Cover). This corresponds to two Pocketbook Era + Cover.
