how to make use of free subscriptions

Hi Everybody,
I have installed moodle and joomla/joomdle locally in my machine...
I have subscribed for Hikashop basic free for 1 year in the joomdle homepage...... and got invoice on it with a key value...
now my question is how I can use it in my system.....because except that invoice i have nothing in my hands....

Hi.

Free subscription does not give access to Hikashop plugins. For Hikashop and other 3rd party plugins you need to get a paid subscription.

thanks Sir....

I have installed downloadable joomdle related plugins in joomla....
For pricing the products in joomdle/joomla what are all the plugins needed..
let me assume that if I'm going to use Hikashop ecommerce..... and I want to know related plugins to be used.

If you get a paid subscription you get access to all the plugins, including all Hikashop ones.
