Needs work

I was really excited when I found this, but ultimately I was sadly disappointed. It only gives you 6 items every few seconds. I keep getting members items. I can’t search for items I know of. The app really seems useless, unless the good stuff is locked behind the pay “pro” wall. Let me see results with an option to only see f2p items and I will resubmit my review. Not will to buy a pro version based off of what I’ve seen.

This app is really good I am able to sell the items based off the prices and it has earned me a lot already.I like how the prices change automatically too so you'll know if there will be profit.

Interesting app

Has great beginner guides and the margin calculator/price filters are rather helpful for someone fresh in the market. However 80% of the reason I paid for pro was the notifications and their broken ("Error connecting to the notification server"??)

Why advertise something if it is not working?
