mrkgnao: Yes. Except that a couple of weeks ago, this scheme stopped working altogether (no matter how many attempts, GOG only returns server errors). I contacted a GOG staff member on Saturday, but got no reply. If I get no reply by this weekend, I am afraid I will have to remove the bundle discount information from MaGog, as it is already becoming outdated.
The bundle discount percentage is shown in the javascript for each product... I'm sure we've been over this before when you first implemented the bundle and there's probably a reason it's no use but..
angular.element(document.querySelectorAll('.module-header--bought-together')).scope().product.series.discountP ercentage
angular.element(document.querySelectorAll('.module-header--bought-together')).scope().product.series.discounte dPrice.amount
Those two links when run in the console will show the percentage and price for the product when bought as part of series..
They return an error / undefined if there is no series.
