Momofuku Milk Bar cookbook for $500 vs Online ordering for $300

I debated ordering $150 worth of cookies, pies, truffles from Milk Bar's web site. But when I saw $180 for shipping on top of the $150, I said screw that and eagerly picked up the new Momofuku Milk Bar cookbook for $18 from iBooks. I said I'm going to stick it to the UPS man and use that shipping money towards a stand mixer

Luckily found a Kitchen Aid 5 qt. artisan stand mixer for $150 on sale from Macy's

But then realized to make these delicious treats I had to get:

Silpat

#16 NSF scoop

Glucose

Special plastic wrap

Airtight containers

Valrhona white chocolate ($17)

Callebaut semi-sweet chocolate chips

Whole Milk Powder

citric acid

King Artur Bread flour

Red food dye

Pretzels

Potato Chips

grapefruit juice

plugra butter ($4 for 16 tablespoons)

local milk

local eggs

Keebler Graham crumbs

etc

etc

Ended up spending over $500 on equipment and ingredients and I'm having a little buyer remorse. Is the $500 entry fee worth it?
