I understand that online retailers need a way to promote what is seemingly a generic product like an Android-based phone or tablet in the minds of the consumer without resorting to price cuts, but this is just sad now. How would you like your sundae. I'll have Product Exclusivity with a double scoop of Limited Availability. Now imagine how much money the pharma industry would make if it adopted this tactic:
"Buy. Or Die From A Disease You (Probably) Could Have Cured If Only You Had Made The Decision To Buy! But wait! we're only going to be selling these medicines right after we cure the common cold. So... sign up for our waiting list to be notified. "
So in short, we need to stop flash sales and start allowing people to buy whatever they want, wherever they want, whenever they want. And flash sales should be renamed to "Here's Something You Definitely Don't Need. We'll take your cash in a flash."
Notice how the Beatles In Mono boxset was initially launched as a limited availability item since 2009. Did they really need to?
