This is just another reason I am glad I bought my nook!
Now when I go into B&N to continue reading in store Blue-Eyed Devil by Robert Parker, I can also get a free e-book. Add to this their discount and two for one Latte/Frappuccino coupons - who has it better.
Are they getting me into their store more frequently - yes
Will I most likely buy something while I am there - yes
I think its a brilliant marketing strategy.
