Hi, I’m Jack; a Senior Copywriter on the vouchers team at Future PLC. Since joining in 2022, I’ve been crafting my money-saving skills in several areas, including tech, entertainment, sports, fitness, home and travel. You’ll usually find me here at MyVoucherCodes; updating users with money-saving hints, tips, discounts, and offers for hundreds of popular retailers. I can also be found on one of our other sites, TechRadar.

A former sports journalist and content creator, I decided to swap the press box for a permanent desk several years ago. Despite giving match reports the red card, I still enjoy attending live sporting events and I like to wind down by playing video games, visiting new places, and getting my head stuck into a good book.
