The "shoebox" approach is quite common, I've also seen an artist who has a cardboard insert that he's cut to fit the lid of his hardshell case with the details (titles, prices) of his current CDs painted on. He leaves the case open, with the insert displayed. at the side of the stage. The swishest setup I've seen is blues singer Papa George. He has one of those shiny cases photographers use with the CDs in and there's a rolling illuminated LCD display on the top with the title and price of his latest CD showing. The Hamsters travel with a display board with samples of their merchandise pinned to it and a roady manning the table.
