Job hunting and had an offer

I recently got an offer as a fresh grad. It's low, but I accepted it since it from a good company and near to me. Problem is there are other companies that are calling me if I am available. Currently doing the company's employment requirements. There hasn't been a contract signing yet. Thinking whether I should continue or risk to other good companies that called me. Been thinking if the being near to me justifies the low salary. Would you still continue or should I just look for another one as I quite of settled because it's near(nearer than others, but still far from me)?

UPDATE: Somewhat, I have been computing on the possible expenses. The results is that there is little difference in what I take home pay. Going far leads me to greater transportation cost. Possible greater food expense too if I choose farther location as where I am located and my possible nearer job might have lower cost from farther from me even though both are in still a bit far.
