My order was $6 short for free shipping at Saks Off Fifth. I noodled around and found a $20 sweater, a basic that crosses over into a lounge wear upgrade. Figuring it's true cost was $12 since shipping was $8, I put it in the cart. That's not really even girl math.

Now I'm asking myself whether in general it would just be smarter to pay the shipping. Do this add-ons ever work out? Or do they end up unworn? I suspect in the past for me it's been hit-or-miss-I need to pay attention. What's your strategy?
