Open a new notebook or page in OneNote or Evernote and start a visual favorites list of certain brands you want to remember.

The next time you head to the store, you'll know exactly what brand tickled your fancy. No more standing in an aisle, scratching your head for 10 minutes while you try to remember that beer you discovered at your brother's cookout last week.
