Difficult to say.....the online vendors use different strategies. Some have higher prices on the items you buy, and flat rate shipping. Others have lower prices, but higher shipping. You'll have to look around. I've ordered from several, but I keep coming back to Midwest Supplies. For me, it's about the service.
