Hope this message is appropriate here.
I have been a member since February of 2013. Initially I input my items manually using Add or Edit items option. Then I edited my items by either using Add or Edit screen or by searching in my booth for an item (I have lost that capability mysteriously lately, comes and goes unless you log out – another issue later!), then editing the item there for description, images, price, shipping changes.
… Lately after many months, I have found the Batch Editor has lots of hidden capabililty that one should learn and use it right away for efficiency. You can search for an item quickly by selecting Update filter or add a new filter, entering a search string, then apply filter. Then your single result or a group of items can be manipulated -modify the price, shipping options, traits, attributes etc for use in Bonanza or another marketplace.

If I need to edit an items description or title from a set (1 or more) of items selected in Batch editor, I use CTRL-left-click on a title to open the item in a new tab (or Shift-left-click to open a new window) and then selecting Edit item. This keeps your original selection intact for further work. I also found out recently (another feature!) I could select columns I wanted to display as well, instead of the default ones.
…To change prices for many items or change shipping options, the batch editor is the easy way to do it with.
… I tried adding text with the batch editor but I found it added text with wasted space at the end of the text. I did not have extra lines in the description. Have not figured out how to add a hyperlink in the text to link to my booth details yet. Searching help did not help. Can that be done as suggested in Help?
.. One last point on editing – It is very important after you make any changes to update your booth if you make any changes to an items description or any information. Otherwise your changes may not propagate out. Just go to Add / edit items and select update booth.
.. One more comment – Just want to say I have appreciated the quick response I qet from Bonanza support in solving some publishing issues I had recently. With patience and many efforts for a resolution, finally was successful.
Hope these comments help …… BestinField
