Thats what happened to my mom but switch the companies...she went to Progressive to from Geico and saved about 1100 a year. My sister and dad left Geico and went to Allstate and my sister's went down 700 a year, my dad about 400.
The biggest thing for me besides the 300 price drop is that I have a $250 deductible instead of a $500 one. I have full tort, instead of limited tort, which f'ed me over in the lawsuit for my car accident that screwed up my back. Underinsured/uninsured went from 25k to 50k, bodily injury or whatever coverage is a a better amount, and it's still less money than Geico. Geico is a ripoff in NJ, I guess.
