You found the outfit of your dreams. if you buy all of the pieces, you will get a discount of 30%. should you buy the whole outfit? you already have a similar pair of shoes. should you just buy the other items (not the shoes) without the discount

Mel - So this is purely in theory, right? 

If you were my kid, I'd ask you how much the shoes were. I actually ask myself a similar question when I get asked to buy a combo- if I want a burger and drink, they'll ask if I want fries. It would literally cost me like .10 for the fries. I won't eat them but I can give them to a student or something so, sure, I'll get the combo. 

Does that make any kind of sense?
