Skyline,
I may have been a little misleading with what I was trying to say, and I agree with you if I was trying to complete an entire set of 1/4", 3/8", and/or 1/2" sockets, for say deep well and short well. But for just this particular 3/8" 6 point deep well set that I am trying to complete, this is the cheapest way that I have seen to get it. This 7 pc set is $49.95 and $4.95 shipping. If I buy all the other 3/8" 6 point deep well sockets (7 more) individually that Snap On offers, I will be in for a total of $245.84 and that is at 8% sales tax. Now even if you add $30 for shipping for the individual sockets, which would be rediculous, I would still save $27.21 over buying 1/4" - 7/8" set through Snap On and adding the rest to make a complete 1/4" - 1" set. That set would cost $303.05 plus tax and shipping.
The way I am looking at stating my collection would be to find a good bang for the buck set and run the numbers to see if it is cost effective.
