at the end of a landingpage I want to give the customer the option to buy the product directly without having to add it to the cart first. There will be three different product boxes for the same product (e.g. 1, 2 or 4 units). This is a very common and useful way to lead the customer to buy the middle option (2 units).
To do this, I need three different buttons with different quantities that link to the checkout directly.
I understand that the "Buy Button" doesn't support different quantities and can't be applied out of the box here.
Is there another way to do it? (Without having to preload a cart)
