Audio / Midi files

[graphicore]

Hi,

 

This is my first post. I am trying to create an OScommerce site to sell my midi/audio creations.

 

I need advice in several topics:

 

1.- on how to enable a way to let customers preview (hear) an audio sample of the products.

2.- Also, is there a way to compress all the selected products when delivered in a .zip file automatically????

3.- When the payment option is PayPal... Can the customer receive the goods after the payment has been automatically verificated via paypal????

 

 

I will appreciate any collaboration/help at this since I am trying to relaunch my old site with this fabulous shopping solution. (www.soundrise.com)
