I just got done setting up my deferred comp (457) plan through work. I was so excited when I saw vtsax as one of the investment options. After setting it all up, I decided to read the fine print on the expenses sheet, the 457 plan company charges .21% above whatever the fund fees are that you pick. Of course I am going to save a lot more on the money put in then .21% but it is insane to me that for just running the plan they charge over 4 times what the fund costs, making it cost over 5x the normal cost at a total cost of .26%
