I actually liked the 4 star store when I visited. Because it stocked items that were highly reviewed it had the peculiar quality of being a showcase for tons of well-rated knock-off items. Like I saw no-name camping and kitchen gear that I had always wanted to get a close up look at to understand the quality and if it was worth the low price. These items were placed right next to bigger name brand stuff too which I'm sure infuriated their marketing and sales teams.
So it might have been a doomed concept from the start, but I'll miss having a physical showcase for cheap knock-off and import goods.
