Right now in Massachusetts regular unleaded is down to $2.09, triggering nostalgic memories of, say, late 2004--those were great times, eh? But infrequent motorists would be well-advised to top off their tanks in the next two weeks. You could save yourself $5, $10, or even $15 in short order!
You might also consider buying twenty or thirty gas cans and filling them up, too. Just don't smoke around them--it's bad for your health!
