Yeah, the one I have was about $30 or so and it came with a few thousand empty capsules.
Plus, it is a nice investment because you can make your own aas orals. For instance, first source on the home page is symbiotics who sells dbol for $25 and one order would be a total of 1.5gr. If you bought the equivalent 1.5gr from a raw supplier, let's say PPL, you'd pay $4.50 for the same 1.5gr. Of course, I'm leaving out shipping costs, fillers and such but you can see how it will still pay itself off within just a few uses... Anavar is usually a pretty big one for saving a lot of money, the dbol is a very conservative example because symbiotic is a pretty good price.
With that said, I have heard that DNP stains so badly that you once you use a capper for DNP you can only ever use it for DNP. I'm not sure if that's true or not... I kind of doubt it.
