Possible to use ConvertKit as the landing page and redirect to another third-party for the buy? (I ask this because I need our cart to accommodate affiliates.)

About You tab:
- Photo: upload a picture of yourself or your brand
- About You: let other community members know a little about you as a person, a creator, and anything else you'd like to add
- Banner: add an image of your creator brand, logo, or an image that inspires your creativity
Social Media tab:
- Let other members know where they can find you and your brand across social media platforms. This is a great additional step to connect with other creators in the industry!

ConvertKit's landing pages are designed to gather email addresses, not to make sales directly. While you can redirect someone to a different page after they subscribe to your list via your landing page, that doesn't sound like what you're looking to do here.

If you need a general sales page, it's probably best to create that on your website, or with a service such as LeadPages.
