If it works as well as some say it does, I think it would definately be a benefit. I didn't use it last year because one or two schools commented that it was not their "prefered" method....but after dealing with trying to get the LORS together myself, it would definately be worth any amount of $$.
...I specifically didn't complete applications at some schools because after sending the LORs multiple times, they still said they had not received them....
