Snap on tool pricing is different from most other sets such as Craftsman.

With Craftsman tools there is a discount for purchasing an entire set rather than each individual tool.

Usually the cost of a set of wrenches, sockets, etc.  is less than half the cost of the items purchased individually.

With Snap On, Mac, Matco and Cornwell if you purchase a set of  sockets you pay the full price for each of the sockets with no discount.

You also pay for the socket rail and each individual clip.

There is no advantage to buying a full set of, for example, swivel sockets.  If you are only going to need a few swivel sockets, then only purchase those instead of purchasing a set.

In the event you need one of those sockets at a later time it is no more expensive to buy them one at a time.

Better yet, purchase your tools on Ebay.  Snap On, Mac, Matco, Cornwell, Craftsman, and many other tools are available on ebay at a fraction of the cost.

I hope you found this guide helpful.
