Ebay seems to be one of the worst offending places for this. Sometimes an item description is written so badly, with no punctuation, and with spelling mistakes so dreadful that you are unable to determine exactly what point the seller is trying to make. I always get the feeling with sellers or commercial websites that we're not dealing with someone, who maybe through no fault of their own isn't very well educated, but rather someone who cannot be bothered to use the spell checking software of which many exist. This suggests that they do not care which makes me very concerned about contributing for their goods or services.
