$ amounts don't consistently save on ads. I ended up having to give away something because the ad showed it was $0. I couldn't verify on the spot because the app doesn't show a complete list of my ads, but I saw that other ads of mine showed $0, so I believed the purchaser. I went back to the desktop version after I got home from the "sale" but I couldn't confirm; however, when I tried to edit another ad, the $ amount didn't show and when I went to re-edit the same ad, the $ amount had disappeared from the field where I had previously entered it. I'm going to delete all my ads now and try another site--I'm glad I didn't try to upgrade, as I would have paid for something that doesn't function properly.
