Olaf: In addition, we can add value through lower prices. As a standard practice, we should discount all books 10% off the publishers suggested retail price. should discount it 25% And for the week after a book appears on the NY Times Bestseller list, we Julio: This means that the price of a book can be constantly changing. You: Yes, every week, whenever the NYT bestseller list comes out, we have to change the prices as appropriate. That is, we need to raise prices of books that fall off the list from the previous week, and reduce prices of books that are new to the list (compared to the prior week) Julio: What else can we do to add value to a customer over a traditional physical bookstore? You: Well, if you think about it, one advantage that a traditional bookstore will always have over us is unstructured browsing where you just look around and buy something that you happen to spot. Where we can add value, on the other hand, is to people who have definite preferences and little time to browse. As a person becomes a member of our bookstore, she can indicate to us the specific authors and/or subjects s/he is interested in and we can then send them messages informing them of new books published that are consistent with their interests. That ill hopefully create demand and add value to the members as well. You: In order not to overwhelm members with e-mails, what we should do is send each member one newsletter message a week (every Friday) which consolidates all the different authors/subjectslists the member is interested in (Note Each member receives an individual message customized to his/her tastes but those newsletters are not tored in the system; instead, they are dynamically created every week). Speaking of that, how does a person becomea member? Olaf: All heshe needs to do is to apply by giving us their name, address, phone number, E-mail address, credit card number. We also would invite members to enter their preferences about what kind of notification service they wish to subscribe to-based on author, subject, or both. Of course, they can always change these preferences at any time You: So you don't need to have actually placed an order to be a member? ulio: No. Membership is, in some ways, a means for us to create demand. However, anyone who actually places an order should automatically be considered a member, with the basic information captured as part of the order process. However, we would not ask for author and subjects preferences at that moment because we imagine that the person wants to process the order as quickly as possible. Once the order is placed, as we discussed before, a confirmation is sent to the buyer and a link is sent to the buyer so that the digital book can be retrieved. You: So we need to have a capability to allow existing members to change their preferences on the portfolio of notification services they wish to subscribe to. Olaf: Actually, we can go a little further. If a person has selected preferred authors, we can ask himher if she wants us to automatically create a new "auto-salc" for specific authors in his/her preferred list. We would still send the member the updates about new books by the authors but, for the selected ones we would create a new "auto-order" as a new book by this author becomes available Julio: If we receive new books by different selected authors in the same publisher list, we would consolidate those in a new order, with each book being a different order item, similar to what the member could do in the more "manual" process. You: That's a pretty unique idea! All right! Sounds good. I will get back to you once I have some initial models ready
