I'm not trying to steer you away from bags but if you're traveling here into coal country the cost for the bags aren't a whole lot less than they are elsewhere. If you're going to make the trip it's only worth it for bulk.
One thing I will warn you about at this time of the year is to make sure wherever you go you call ahead of time to make sure they are selling to the general public. Supply starts to get tight at this time of the year sometimes and the public is the first to get off.
