Download Credits

I have gone to all digital downloads for my sports team photos. I do pre-sell where downloads  are cheaper than you can buy on the website so I then go and add download credits to the accounts.

However, the download link does not appear until a person clicks on one of the packages. Package D  gets a link to download for  1 credit, Package C gets a download for 2 credits and Package C is download for 3 credits. 

I am telling people to click on Package D to get the download link, but some people don't read directions and click on the package they bought and use up their credits.

How can I get this to work correctly?

There is an option when editing your products  "Collapse Options & Descriptions". If you uncheck that, they won't have to click the product to see the download option. It will show right on the screen.
