Kollade efter lite extra noga. Mitt evisa är från december 2013 så ca ett år sen, det tog 3 dagar att få. Det kostade 28 dollar och fotot tog jag med min egen telefon. Man får ett mail med sitt evisa i pdf format. Priserna har säkert ändrats enl vad andra skrivit ovan.

Lite övrig info i mailet med visat som kanske är av intresse:
