Hi,
I also need this feature, if it is possible.
I would like use only the quick buy function on our site and redirect the customer right to the Checkout page, and never use the cart page. Like on this page:
https://www.admincolumns.com/pricing-purchase/
If the customer place a product into the cart, and redirected to the checkout page, but he does not buy the product, then the next time when he choose a product, the previous product should be removed from the cart.
This is important because if we do not use the cart page on the site, there is not any possibility to remove any previously added product from the cart.
The following code is useful for this reason: https://stackoverflow.com/a/27031767
This code can be applied independently of this plugin, but it would be more comfortable if it was a built in function.
Maybe it can be switch on/off globally, or just for specific shortcode buttons using a shortcode parameter.
Thanks in advance,
Pal
