These days everyone it seems uses a mobile smartphone using apps usually free or less than $1 over that amount would seem excessive even $2 os let alone €30.
€30 ($43 + taxes Canadian to me) that's quite enough for software maybe not excessive but any more and I'd pass on it.
Having purchased a computer in 1990 along with WordPerfect ($300 then - $540 in today's dollars) and Lotus 123 (another $300/$540), this makes me smile ;-)
