Can your company provide 20 units or lessat a time How current are your collegebook titles How long will it take to ship 10 to 15books to Chicago !!MOST IMPORTANT!! Can you provide adigital version of a college textbook Most of all I would like to purchase college textbooks from adigital file such as a PDF or Word document. I have done businessbefore on Alibaba with college textbooks. I found that shippingcost and time negatively affected the business. You can save *on print cost. Both our business can save time and * if we DONTneed to ship anything. If I can negotiate a price per file thatwould be fantastic. Thank you for your time and I hope you respond.Im very excited to be back in business.
