I have a product where I want to increase the price gradually, e.g.
- first 100 sales = $10
- next 200 sales = $12
- next 500 sales = $15
- all remaining = $20
Ideally this would be the same product id, as I only have one product for sale and my shop is setup to redirect to this single product as the start page.
I'm using Journal 2 theme with opencart v126.96.36.199
Is there any extension like this?
