Registration from Landing Page


I am planning to create a Landing Page from where to offer a registration discount that should not be shown in my current membership-options-page. I am using s2member basic/free plan.

My question is if it is possible to place directly inside the landing page the PayPal button that is normally created by S2member thus allowing the person to automatically enter the platform as a registered user and without issues, (avoiding registration steps as much as possible)
My main concern is to offer a fluent experience from landing page to the inside of my platform.

I have read in the forum Raam Dev´s post at *“You can create pages in WordPress and then show them to users upon first login using Dashboard -› s2Member® -› General Options -› One-Time Offers (Upon Login).” Unfortunately, I don´t see this option in my s2member version. I am not completely sure, though, if this is what I am looking for. I am just looking for an alternative place where to place the regular Membership Options Page -->PayPal buttons.

Any tip will be much appreciated

Thank you in advance, Regards
