Register and receive an offer

Hello,
in a test with a coupon everything works as I want it to. I have given some plans a 20% discount, so in order to receive the discount, members ultimately have to enter the coupon word as well. The purchase is then recalculated. And that's how it should be.
Now the problem: If a person wants to register, no field is finally displayed to enter the coupon word. But that is needed to get the offer.
I need help there, please.




Screen: In this case, someone would like to sign up for 3 months.

Coupon is entered during the checkout process when viewing the basket. It's not entered during registration.

Thank you for your prompt reply,
So a new user first has to register and then can upgrade his membership? Mh, that's not so nice. I advertise using a link to an offer. Now of course the interested party thinks that when they register they will also receive the offer ... That is confusing, I think.
Can you show me a way how a user gets the plan directly when registering for which an offer exists (I want to use coupon).

Best wishes

CBSubs can't work without a user object so yes they have to register. After registering they'll immediately be taken to the basket page to complete their purchase and input any coupons they may have.

I don't know what you mean by this, sorry. You can't use a coupon until you're able to enter the coupon, which is done on the basket page.

Thanks, I've adjusted the strategy. Subject can be closed.
