I've a question to people following Ariely & co's work: Is there anything there that might help explain why people have no problem paying a few bucks for coffee at Starbucks, but not for, say, an iPhone/Android app?
(I use the Starbucks example since most consumers don't hang in the coffeeshop, so no experience or particular quality involved, just a cup of coffee that lasts a few minutes)
Also probably some relevant tips for giving good gifts. It's holiday season after all.
It's still the closest I've been able to come to explaining the added value of quality copy.
