After you pay the trainers you can pickpocket them for your money back. Gold is automatically subtracted from the inventory when a training session is accepted. All training requires that a fee be paid.
Skills can only be trained five times per level, until the skill level exceeds the level of the trainer. Most trainers offer their services from the start of the game, but some require certain tasks to be performed first. Trainers are NPCs who help increase proficiency in skills in The Elder Scrolls V: Skyrim.
