I've tried various methods of making the 'download only' info obvious. I've always kept it right at the top of the page, right next to the link to purchase (as well as info below in the 'features' section which states "no waiting for the mailman to deliver it".
http://www.schoolofpuppetry.com.au/tutorials.php/how-to-make-a-muppet-type-puppet-human-foam-puppet-patternI've often rearranged things, and over time, added capital letters, bolding, and the "questions" link to the policy/refunds/etc page.
As with my past issues using Lulu, invariably this problem comes from people who "assume" that it is a hard copy (ie. they seem to be in a rush and don't take the time to read policies... which I find strange because I always read stuff before paying). (Most customers spend less than 10 minutes on the site before buying and never read the policy page)
There's really only so much I've found I can do. (It's unfortunate I can't redesign the Paypal payment page so that it can have the info there as well)
As for ensuring the email goes into the inbox and not the spam, once again, that requires people ensuring they read this stuff.
What has me scratching my head the most is that even if they assume it's a hard copy, or don't get instructions via email... they never contact me about it anyway. I've had customers screaming bloody murder for not receiving info 2 seconds after making a payment, and then I have customers who disappear...
Anyway, returning to my actual question: I know I have done due diligence, but I guess I have an objection to keeping money when I know people haven't received the service they paid for. Perhaps it's because I know I'd be extremely annoyed to discover I haven't, and have been in the past. At the same time, there's a difference between when I've not received what I've paid for, and not *accepting* the item/service due to missing an appointment/typing my email wrong/whatever.
... Which I suppose is the point. A more aware customer reads the info provided, remembers what they paid for, where they got it, and who to contact when it doesn't arrive. And if they're aware of all that, they'll also be aware of when it's their responsibility to follow up.
Still the question is an interesting one, at least for me, because I always equate downloadables as a different kind of service to a physical product: and in the eyes of the law, they're pretty much the same.
Disclaimer: as I'm aware potential customers/former customers can read this... at no time am I thinking that anyone is a fool. I'm more than well aware that life isn't perfect and sometimes we forget to read policies or mis-type an email, or miss seeing important info, or that the layout/design lends itself to missing such info. I just find it very frustrating is all. I like to do right by everyone!
