If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
Custom PayPal buttons are a great way to go however even if you are using the Yola Online Store Widget your customers can still buy multiple products. Once they add an item to their shopping cart they can either proceed to checkout or they can "continue shopping" which will return them to your website. I have attached an annotated screenshot of the shopping cart from my Yola for your reference.
