Works with CiviCRM 4.7 and should work on CiviCRM 5.0 or higher
When people sign up for an event, you may want to offer registration for an additional event or membership dues while they're checking out. This extension ties event registration or membership to a price option, so you have full control over the price--potentially offering a discounted bundle rate.
Many thanks to Maggie for the initial development.
