Where can I find synonyms

Hi,

Sometimes I need to use synonyms as using same word again and again makes the paragraph boring, e.g., I need a synonym for the term "as well as" where can I find it. Here is the sentence where I will use the term:

XYZ company is quite popular in WB as well as in India.

Please help me rewrite the sentence in a better way.

I appreciate your prompt response to my query.

I do use MS Word and Word Web...these are really helpful to find synonyms, however, as these are mere software, they often fail to provide the exact word that I look for. So I wanted to check if any collaborative online resource is there or not.
