I still think putting Repel in the department stores only, would give it a unique touch. There is a rather high demand for them as I read in the help channel recently. If potions, super potions and max potions are sold there, why not Repel? I'm not just putting the item REPEL out there for just adding something to the topic at hand but it could be very handy in, let's say, Bell Tower. I have a bad connection and i'm laggy. Because of that i'm pushed back 5 blocks and have to re-walk on them, and for that duration encountered 2 Rattata after each other. This goes on for minutes. What happens now? RAGE FACE. *Mumbles* Wish I had a repel right about now.
Another thing is, if this basic necessity was implemented at a department store, wouldn't it spark the interest of what other compelling items/commodities the store might have?
Here's an idea:
If you want players to visit the department store often, why not place an item there that can only be bought once that they won't get to buy anywhere else. This item should be an important accessory. They can only purchase one/two of these at a time.
Just a suggestion.
