The reason there are 2 VIEW CART buttons is because we are in the process of converting all of our older sets dating back before January 1, 2013 into instant downloads.
So anything you purchase that is released from January 1st 2013 up to today will be instantly sent to you after payment is made. All of those sets that you order you will find under the GREY VIEW CART BUTTON:
You will receive an email (to the same email used in paypal) with a link to download your order. This email will come from a company called Fast Wagon.
All of the older files that have not yet been converted into instant downloads you will find those items in the YELLOW VIEW CART BUTTON:
So if you are ordering a few items from both of the instant downloads and non instant downloads, you will have to pay two different invoices (both will still be through paypal).
