# My friends have HPAT Premium Group packages. How can join their group to get the discount?

In order to join your friends who have already purchased the Premium - Group package:
* Purchase a Premium - Group package. You can add extra items to your cart without affecting the group 
* Your friend must invite you via email to join their group, using your **EXACT** MedEntry registered email address
* Login to your package, click on your name in the top corner, then My Account and finally My Group.
* Click the 'Join a group' button and enter the group number sent to you in the invitation email.
**NOTE: You can only join a group if your registered email address is identical to the email address used to invite you to the group.**
If you haven't purchased a Premium - Group package, you won't be able to join the group.
**Please note that group discounts cannot be obtained retrospectively**, that is, if you purchase the Premium - Individual package and later find a group, you will not be able to obtain a group discount / refund.
