STEP 4: (optional) Clear your basket and cache.
- Well, at first clear your basket. It is very usual, but necessary operation. Simply right click on your basket and choose "Clear".
- After that you have to clear the cache of your browser. For example, if you use Mozilla Firefox as I do, just go to menu Tools and run Options. Open Privacy tab and check option 'Clear history when Firefox closes'.
- Then click Settings at this screen and check options 'Cookies' and 'Cache' as shown at picture.
- After that click OK and close your browser's pages. All information in cache will be removed.
