• The Jamroom Store, which is part of the Jamroom Core, allows your artist profiles to sell "physical" items, such as T-Shirts, CD's, etc - it does not allow the user to sell "digital" items (such as an MP3 download).  It is a very simple store - each item is created as a "Buy Now" PayPal button, that when clicked on by a visitor will redirect the visitor to PayPal so they can make payment.  There is no shopping cart support, and the email address that the payment is sent to is the email address that the artist enters into the form when they create or modify the item for sale.

It is the responsibility of the profile owner to ship any items purchased, unless the Jamroom Quota the profile belongs to has been "overridden" with a PayPal Email Address that has been applied to the entire quota in the Jamroom Quota config - then it would be the responsibility of the owner of the quota PayPal Email Address to ship any physical goods purchased through Buy Now buttons on profiles in the quota.

• The Jamroom Vault (which is part of the Jamroom Payment Pack add-on) allows your artist profiles to sell digital items - i.e. MP3 files, video files, photos, - anything.  Jamroom supports dozens of file extension types.  This is integrated with a Jamroom shopping cart, so visitors to your Jamroom can select multiple digital items they want to purchase, then "checkout".  These items are not available to users until they purchase them, and the PayPal transaction is sent to the Jamroom site owner instead, who can then distribute funds to the artist profiles on a scheduled basis with Jamroom's assistance.
