You can see there is a wide range of pricing options from the ComponentOne Store  .   Support subscriptions, upgrades, the complete Enterprise Studio or specific individual Studios for  .NET, ASP.NET, etc, on CD or download

  And you can of course also purchase some or any of the individual components.    As you will see from the price list, if you are going to buy two or more then in almost all cases you will get much more bang (or components!) for your buck if you go for one of the Studio packages or even the whole Enterprise edition.   You will effectively get twenty or more additional components for no extra outlay.  (that's certainly an improvement on the standard "Buy one, get one free" deal!)
