The problem you may have is that SF probably reports all claims to an indexing system. So other carriers will most likely see that you had this policy and had 2 claims.
Probably? No, definitely. It's called ChoicePoint (a LexisNexis product). Any and all claims get reported there, just as delinquencies on your Amex shows up on Experian for Visa to see.
There is no free lunch.
Having a $100 claim may seem trivial, but for a massive insurance company like SF, the sheer overhead cost of processing that claim was probably several time the payout.
$60/yr isn't where SF makes its money. It's when you are in their sights for the PAP that they can market other products (like a loss-leader in retail). Even if you don't use them for anything else, they can still make money after a claim by using your now-blemished record to justify higher premiums.
