We work with Google based on wholesale model: publishers set a digital list price, but in the end the retailer (Google) sets the final price for ebooks. Google is usually trying to sell ebooks cheaper than any other channel, discounting the books at a pseudorandom way, depending on price and currency.
Being aware of the Google discounting, we automatically adjust the retail price given by the publisher to avoid price matching by Amazon. Our algorithm tries to keep prices in line with the Digital List Price.
Payment will be based on Digital List Price.
