So from what I can tell, the Fresh Finds Shop is meant to be NA's version of the Treasure Shop from JP. However, it's very unintuitive, and to put it bluntly... It's also just ugly.
My suggestion would be to ditch the low-res hypercompressed ad pictures for the "major" items and grid layout for the minor items and just make it like the normal shop interface, with the items clearly listed and the real-time character preview.
