"such as" is usually used to introduce examples meanwhile "like" is used to show similarities. casually people use "like" also to introduce examples, but in proper grammar, it shouldn't be used that way. 1. Can you buy me some fruit like apples or grapes? the above sentence is WRONG because it would mean that the speaker does not want apples or grapes, instead some fruit that is similar to apples or grapes. 2. Can you buy me some fruit such as apples or grapes? the above sentence is CORRECT. apples or grapes are examples of the type of fruit which the speaker wants.

Looks like both of the above answers are on target. Rob
