What I'm proposing (I haven't checked if it's been suggested before btw) is a link within each Item on sale (see image) I assume there is a list of currently owned Locos/Rolling Stock/Routes/Scenarios within the RailWorks files and surely there is a way the website could read this? It is such a ball ache searching through all your Steam DLC/ JT direct bought DLC and so on just to see whether you've already got the GWR Pannier Tank Pack Add-on for example.. Would save a lot of refund request tickets for "duplicate purchases" too I would imagine.. Anyway I'm just the pretty one with the ideas, you lot are the clever ones with the solutions..
