MY QUESTION IS DO I GET MONEY FROM THE SELLS FROM MY STORE AND HOW? IF I SET UP A STORE MY WIFE AND THINK ITS A GOOD IDEA . TO DO THIS

The RCU store is only a store front. The handling of money between buyer and seller is still handled by the buyer and seller. How long it takes for you to get the money will depend on what type of service you offer for payment and how the company you use for that service processes the money to move it from the buyer to you, the seller. Paypal offers web payment services as do many banks.
