Also, another thing to try is to , in a sense, close and reopen the app. This will NOT cause you to loose any data, your game will be saved, but it will sort of reboot it. To do this..
1. While exited from the app, double click the home button. This will bring up all the apps that are "active" at the bottom of the screen.
2. Press and hold the VF2 icon that is located in the " active apps" bar until the apps start to wiggle.
3. Press the red minus sign on the VF2 app. This shuts the app off, to create the "reboot" effect. ( do this with any other icons that show up if you wish, this will help with data usage and device efficiency)
4. Once you have cleared what apps you wish to restart, press the home button again to exit.
5. Check and see if this helped! If not...

The flea market, sale items, and clothing items are all based on your clock on your IOS device. If you have made a change in the date, time or year via your settings, this will affect the game. Make sure your date and time are correct and "reset" your settings app and the VF2 app.

Hope this helps!
