Plugin wordpress random product select.


I have a website [ made in wordpress ] where i sell license keys for digital products [ games / anti-virus / softwares etc ].

In back of website i use License Manager for distribution of keys.

I have some Keys that i put them togher and i want to sell cheap. This script should allow me to add multiple licenses and when a customer buy “Random Product” he will get a key randomly from what i will add in a specific list.

Is there something that can do this?
