What do I buy

What do I buy, am I being extra thick this morning because each time I go to the store to purchase 2016 its show as £99.99, I have checked on Steam and its shown as TS 2016 steam edition at £24.99, when I put it in my shopping basket it tells me I wont get all as I already own most of it,all I really want is the updated Riviera line and locos which if bought as a separate route would still cost me the same amount, so is the one I need the steam edition as I don't want to give DTG anymore than I have to on top of the small fortune already spent,

Rod.
