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!
Yola doesn't offer such a feature at present. Have you tried to find something that suits your needs by searching on the web? If you find a provider who offers this feature to embed on web sites, using HTML code, it's very likely that you will be able to add it to your Yola website by using our HTML Widget, too.
Maybe some of our users can help you on this thread if they know about an auction feature on the web.
