Insert coupon after registration/login

[yuri@.....it]

Hi, I have several coupons that can be used only once by a user, so you need to register or login before you can use it.
1. Would be possible to create the account immediately when you click on "create accout"? (img1)
2. Would be possible to display the coupon box only after registration or login? (img2)

Config: Joomla! 2.5.19, VM 2.6.0, One Page 2.0.244.130514 - template:band_box

Thank you in advance
Best regards
Yury

hello yuri, if we add registration over ajax, this would really make your site vulnerable towards spam attacks and would not be an ideal solution, but we can think about this request for the future.

do you have any particular reason to dispaly the coupon functionality only for logged in customers? in opc even when guest checkout is disabled, in cases when already registered username/email is used the checkout is still possible to prevent as many problems as possible.

best regards,
