My two cents: Shops could have certain items available for purchase for a limited time, say one week. After that week they'd be removed from the shops. This would create some rare items later on in the game. I don't see a problem with this approach, if we're given enough time to earn the credits to buy said items. The problem with most of the rare items on VMK was cheating to get them and scamming younger inexperienced players out of either their rare items or everything they owned. Trading fairly is difficult to regulate, perhaps impossible. I was never really into trading for anything. Everything I had on VMK was either earned by playing the mini games or given to me by friends. Did I have rare items? Yes. Would I have enjoyed the game without them? Yes. Maybe one way to keep things fair on the new version would be to have moderated trading. This way nobody is cheated.
