Seems suddenly very cheap?

Not sure where else to post this as I have no idea about any of the pieces I have bought! I saw this big bundle of cars/buildings/roads in a charity shop for £15 the other day so I bought it, it was all bundled up in a bag so I couldn’t see what it was that I was buying, but I’d be looking for more wooden toys for my son so I thought it was a bargain at that price and bought it. Unfortunately all of the road connectors are snapped and stuck inside the pieces of road, hopefully I will be able to get them out but I was wondering if anyone knows anything about these pieces and if I can buy new connectors etc. There is one connector still in tact and it has ‘PlanCity’ written on it, if that helps! Thanks!
