In his previous post, Paul has the way on how on access the Preview already, so here are the instructions also:
(1) Go to the price grid list for the REA auction here:
http://bid.robertedwardauctions.com/pricegrid.aspx
(2) You'll notice in the drop down list box, there is an option for CURRENT AUCTION: REA Spring 2012. Choose this option, and hit the Submit button.
(3) You will then see the lot grid for each lot for the current auction. (All w/ $0 prices). You'll need to manually click on each lot, to see the preview for it.
Manually, painful, but, hey you can see the preview.
