Irresistable offer that makes us buy things we don't need.
Buy more, save more.
FREE to attract people to go inside the store (Borders Book Store).
People just went crazy for FREE stuffs, even if they needed to spend $200 or &300, which they didn't plan to spend before they came here.
Will you wake up earlier to travel for FREE?
Which one do you think is more attractive to you: 2 for $10, or Buy 1 FREE 1? I'd go with the second one. FREE is just irresistible.
Things that we don't need but as humans, we are intrinsically afraid of loss. So we don't wanna lose this offer.
Is this really the best deal? Most of us won't think twice when we see 'Best Deal'. We assume it's always the best deal. For this case, I went to the nearest Supermarket, and it was a best deal. We would save $1-$1.5.
Wow, they'll give me $50 for my old jeans. I can't miss this offer! But then, I'm gonna need to add another $50-$80 to get a new one.
It "forces" us to buy things that we don't need, just to get the FREE item.
This kind of thing makes people wanna shop like there's no tomorrow.
