Add-on upsells

Which of your products offer an option to add on or up-sell a customer as they are in the process of checking out? Forexamplye they have decided to register for an event (free of paid). So after they complete a portion of the form perhaps the name and email, thenthey get an option to add a membership (membership pro) or add a book purchase.So its a landing page, 2 fields form to gather lead or close out sale and check out, offer up-sell product and checkout or even offer another up-sell before check out
.
Many may not buy the add on, but then others will. I have sold a few books that way by adding a "purchase book" up sell radio button/cart button via paypal (didnt want to go via paypal)

Any ideas how I can make this happen using os solutions tools. Thanks.

Hello Sobem

I don't really understand the question. However, maybe you can use Events Booking in this case? For up-sell options like that, maybe the custom fee fields feature can be used to handle, see documentation at eventbookingdoc.joomservices.com/basic-s...wn-custom-field-type

See domo at joomdonationdemo.com/eventbooking/featur...ividual-registration
