The deductible is not a discount, it's the part of the accident (or whatever damage) that your policy does not cover.
If your policy costs $2300 a year and no accidents happen, you still pay $2300 that year. If it costs $2300 and you crash your car, it costs $2300 for the year plus you pay the $1000 deductible.
But yes, all insurance companies offer discounts. The more desirable a customer you are, the more discounts they'll offer you. Your best bet is to call an insurance provider or six and compare them around, and be sure to ask them what the hell they're talking about when they mention stuff like deductibles, liability limits, optional coverages, and any of that other mumbo-jumbo language they use.
Any idiot can say "it costs this much, sign here", only a real professional can tell you what you're signing in layman's terms.
