No, they aren't different in content. If you go through their buying guide and click on "What's This?" next to resale option, it says:
"Digital Edition (DE) products are licensed for one family only, and that family gets to use it for all of eternity (or until their school years end, whichever comes first). DE products cannot be given or resold to another family because of industry-standard software (or ebook) copyright reasons. If being able to sell your copy of Tapestry products once you're done is important to you, you need to choose the print-only format. The paper copy of the curriculum that comes as part of the DE + Print Copy option is not resalable because it's purely a paper-and-ink copy (that we are happy to permit for your convenience) of your DE Tapestry license."
beth83, you have received several good replies to your question. I will throw something else out there for you to consider also. If the print copy with the DE were resalable then any one of us with DE could just print off copies and resell them. There really is no difference there when you buy a print/ DE combo. Yet another is that when you buy a print with the DE, it is just that, a printed copy. For that specific printed edition, you have not paid the cost of the curriculum. As far as monetary value for Lampstand Press, it is just paper with printing on it. Just look at the price difference between the DE/ print combo and print only. This is very well explained in the quote that Kathryn has included here.
So, I don't get this. Why can't the DE/print version be resold? I just assumed it was the print version you can buy alone, plus the DE version. Why can't you sell the print version from the DE pack if you can sell the print version if you buy it alone?
I'm guessing, now, that the two print versions are different? How? Why?
