If I bought a book at Barns and Noble, is there a way to get it on Nook for free?

I have the receipts, and i am using my android app on my phone. It also has a barcode scanner, if that helps. k thankz.|||The bar code is for one product, a printed book, and the e-book is a different product. The only way to turn that printed book into an e-book is to scan every page with OCR software. Considering the amount of time that would take, not to mention the poor results and the cost of half-way decent OCR software, that's hardly free. You could sell the printed book and put the proceeds toward the cost of the e-book, just read it in print, or else download an app that supports library e-books and borrow the digital version to read.
