There is a very interesting post over at HighRankings on an issue found where Google is highlighting some of the words in the Google Cache results but not others. For example, this Google Cache with the keyword "Cedar Chest" highlighted shows most of the words with "cedar" and "chest" highlighted but not all. If you look in the middle lower section of the page, you will notice that the same words are not highlighted. For a clearer representation of what I mean, click here for an image.
One possible reason mentioned in the thread is that the content found within the noscript tags are not highlighted. When you view the source of that page in the Google cache, you should notice that the middle content is found within the noscript tag. Do a find on noscript and the prices within the page, so they are surrounded by the tag. But yet, the Google Cache shows the contents of the information within the tag. In addition, I thought the information between the noscript tag only displays when JavaScript is turned off. Any ideas on how help the person, join the thread.
