Pretty cheap from your local auto parts store, or you can soften the old ones up by annealing. To anneal heat up with a gas torch till 'cherry red' and drop into water. This softens the copper up again .

As Deano says - annealing works great with copper washers. Just watch that they aren't getting really thin (ie thin enough that they are likely to break/split when you do them up). Can happen if the've been done a few times before.
Domestic gas stove will get them hot enough too if you dont have anything else.
