I haven't purchased a pBook in several years. I probably WON'T purchase a pBook again - unless it happens to be a required school textbook, or a hard copy of Twilight with autographs from the entire crew....
That doesn't mean I don't enjoy walking through a book store and looking at what's new. Just like I walk through new car lots occasionally to see what's out there...or furniture stores to see how cheep they are actually making this stuff and how much they want to charge for it...
If I see something I like, then I will make a mental note. When it comes time to purchase -
IF I decide to purchase - I will then find that item for the best value/price I can. It's called shopping around. If it happens to be a book that I saw when I was in a store a couple weeks ago, and I can get it much cheaper on Amazon/BN/Bubba's Bookstore, I'll use them.
Just because I see an item on a showroom floor in no way EVER obligates me to purchase that item from that store....and it is in no way EVER considered stealing/shoplifting/unethical ...big brother/government hasn't mandated I buy from a bookstore I just stepped into...yet
