I use the checkout-x app, which I find very good.
On the other hand, this app has a huge disadvantage: it doesn't integrate bundle apps, nor pre-order apps:
all the discounts generated by these apps are not redirected to checkout-x.
I asked checkout-x to do something about this but nothing to do.
However, I can imagine that there can't be much to do to make it work... But I'm not a coder...
does anyone have any advice for me (apart from changing apps ahah)?
