Don't get doweling at a hobby shop unless you can't get them elsewhere. All wood products are usually at a premium price. Best to get doweling at a wood craft store, Lumber Yard, Even some large hardware stores (Lowes, Home Depot).
The volume that these stores buy wood at reduces the cost. Hobby Stores only buy a little at a time pushing there costs up. It is true that the really small dimension wood can only be found at hobby stores though.
