Looking to create a shopify website where the price of an item decreases as more people buy. I.e. the item starts at $10, but if 20 people buy it goes to $8, and if 40 people buy it goes to $7.
I will create the website, including front end design, I just need this group buy function. If there is an app that already does this, or an app that can be used and modified that is OK.
An example of a site using this is weargustin.com. Basically I want o duplicate this site, but make it so once a buying level is reached the price goes down
