An ingame Store?

Hi i made a game called FedEx Office at http://www.roblox.com/games/346861277/FedEx-Office and im planning on adding a Package Ordering Station where there will be a shelf with all the types of packages in the game and what it looks like. And i want to know how to make it to where the player can click on a type of package and buy it with ingame points and have it notify people on a certain team to deliver that type of package to a certain house the player who buys it chose.

Example: I chose to order a small FedEx Package with 10 Points. I chose it to be delivered to House 2. The people on the team "Delivery" get a notification to deliver a small FedEx Package to House 2.

I have 8 Teams in this game.

Neutral, Front Desk, Delivery, Storage, House 1, House 2, House 3, House 4
