I'll start with what I don't like - the books say one price online but are more in the store.
I presume the difference is to cover the brick and mortar, and I for one don't want to be explaining in a few years how there "used to be" bookstores like I've done about ticket outlets, record shops, and diners.
What I do like: while online you can reserve a book for pick up in store. There is a 60 minute timeframe for the store to get your book. I had a text in 20 for mine. Staff are friendly, the cafe is nice, the place is spacious, clean, and well lit, and you can spend casual time here if you like.
Or like me if you've got no time you pre-order, get the text, and be in and out in 3 minutes.
