I currently get a daily email from gospelebooks.net that keeps me informed of all the Christian eBooks on sale for the Kindle. I have found it helpful in giving me a heads up of what Vyrso books are going on sale. However, it would be much more convenient for me and others just to get an email from Logos/Vyrso each morning listing the books that are on sale with links to the books in the email.
Related Suggestion: Please try to negotiate with the publishers so Logos/Vyrso can participate in all of these web sales. We much rather purchase from you!
Related Suggestion #2: Consider including Logos books, even if you have to charge more. I have noticed that often times Logos/Vyrso in not meeting all these sale prices because some of the volumes have moved from Vyrso to Logos. I know I do not mind paying more for the Logos version. So for example let us say that on average it cost Logos $5 more to produce and maintain Logos books (simple books, not commentaries/dictionaries/other heavily tags book), I would choose to pay $5.99 for a Logos book rather than $0.99 for a Kindle book every time. I think you will find most customers will appreciate the fact that you attempting to match the SALE, if not the price. Logos books are worth more to us, because they are better! However, there are limits, a certain point it become hard to justify the Logos price. I hope this makes sense.
