Thanks for commenting on this. The Auctiva Emporium store, which automatically shows all your active eBay listings at any given time, was not designed to show the Best Offer feature so it is expected that you are not seeing that option option displayed next to listings which offer it on your Emporium page itself.
However, if a perspective buyer who is viewing your Auctiva Emporium clicks on one of your items, he/she will be taken directly to that listing on the eBay website and will be able to see the Best Offer option there if it is available.
Unless you specifically promote your Auctiva Emporium using the address provided in your account, most of the traffic to the store will most likely be from perspective buyers who click the link to your other items in the bottom-right corner of your scrolling gallery, but you may get some traffic from search engines as well.
If you would like to remove the link to your Emporium from your scrolling gallery, you can do so by mousing over the “Gallery” tab, selecting the “Customize” option, clicking the “Text & Placement” tab on the ensuing page, deleting the contents of the “Bottom Text” field and then saving your changes.
If you make that adjustment to your scrolling gallery settings, the link to your Emporium should no longer be present in the scrolling galleries in your listings the next time the scrolling gallery refreshes, which it does approximately every 2 hours.
We appreciate the feedback and have made note of this idea as something to consider when we are planning future site updates.
