I don't think this is such a good idea, but here is an alternative:

I got both the vision and the dental Family plans for about $80 per month in Alabama. The plans and the cost is different per each state.
But when my daughter and I went to the Eye Doctor, the amount we saved from one visit was half of the cost of our yearly premiums. So this insurance has almost paid for itself in one eye doctor visit. I haven't even started on dental work yet.
