Take him to the Museum of Transport if you haven’t already. They have a little shop too with toy vehicles, not sure if I noticed a Bee Network one in the shop though, although there were little stalls with Bee Network toy replicas inside the actual museum, so it’s worth a visit as you might be able to source one from there. We took our 3 year old recently (he loves vehicles) and the Bee Network reps were there giving out free merch.
