I’m building a Shopify that sells VIP tickets for a 3 day event. There are 4 tiers of VIP experiences, each tier has a 1 day, 2 day and 3 day option available for purchase.
Tier 1 is called “In the Paint”
Tier 2 is called “Varsity”
Tier 3 is called “Starting 5”
Tier 4 is called “All American”
I initially set it up to where each tier has a 1 day product page, a 2 day product page and a 3 day product page.
BUT, the client wants to simplify the checkout process by only having 1 product page per tier. The customer can then select the 1 day option (and choose 1 of the 3 days in a dropdown menu), or the 2 day option (and choose 2 of the 3 days in a dropdown menu), or the 3 day option. All 3 of these options have a different price points.
Can someone please walk me through how to do this? I’m assuming this will have to be custom code. If not, please explain as I am just a designer. 
Thank you.
