I went to the Photography Show a couple of weekends ago where they were selling Affinity Photo for £29.99 until the Tuesday when they finished. When I went online to purchase they were advertising a 25% discount on iTunes from £39.99, so they should have charged £29.99 as promised. I contacted ITunes to complain and they asked me to contact you, so who is to blame for the overcharging and when can I expect to receive a reimbursement?
