Hey, I’m Matt. I first joined MyVoucherCodes as a Deals Expert, scouring the internet and leaving no stone unturned in finding the best discount codes, sales, and offers for our customers. Moving into my first home during the worst possible time (during lockdown) I understand the necessity of saving money when the purse strings are tight. I’ll do my very best to save you money wherever I can.

Outside of saving money, I’m into video games, movies, books and music. I host and edit a video game podcast called The Retry Hard Podcast, where my friend and I go through news, reviews and video games in general. I love movies and watching how they’re made,  and I’ve worked as a set decorator for a few months on His Dark Materials season 3, which gave me a massive insight into how it all comes together. I also put out music through my pop-punk band, Truika, and as a solo artist under the name Matt Kiano, where I won Best Male Artist of 2025 at the Radio Wigwam awards.
