I know, they are not very high capacity, but if you have some of the older Olympus or Fuji cameras, this is the largest card you can use in them, and the price is great.

Buy.com also has them, but the checkout at buy.com adds shipping to each card, if you go to JR you get one shipping charge for the entire order.

Of course, if you have a camera that can take a higher capacity card, there is no need for buying these
