The ebay store was still there but only had 1 item listed when they opened their own online store. I think over the last couple weeks, the changeover didn't go as smoothly and now it seems most items are back on Ebay as well as their own online store.
My guess is they saw a drop in sales since no one knew what happened to their store. My bet is they will maintain both for a while. The Ebay prices are slightly higher on some items.
