Mr G Enterprises - Bolt Kit

Has anybody used the Mr. G "Mopar Underhood & Trunk Bolt, Nut, U-Nut, & Screw Kit"?

The one I am looking at has 215 pieces and costs $179. I am think this would save a lot of time instead of going back and forth to the Hardware store. But, seems kind of expensive. I am not sure if it is worth it?

Here's what is included per an email response from Mr. G
"[FONT='Helvetica','sans-serif']The underhood and trunk kits will include all visible bolts, nuts, u-nuts, washers, and screws under the hood & trunk less the motor and lower suspension items, plus it includes fender bolt u-nuts which are not technically visible"[/FONT]
