Please is there any possibility to show product_sku in shopping Cart? it is hard to explain why (marketing and tracking reasons = other logical solutions does not work for us, so we have to do it how we can..)
hello, the OPC themes can be selected at the display tab and they are located in /components/com_onepage/themes/{your selected theme at the display tab}
you can choose a one that shows the SKU within the cart or you can move the SKU section from a theme which already shows it.
the basket rendering is done in /components/com_onepage/themes/{your selected theme}/overrides/basket.html.php
