Dáwñ: i dunno .. my opinion is people are getting sick of over-priced used crap .. you used to get 'good deals' on ebay .. now your pretty much better off buying new at amazon on most things .. thats what the 'strategy' your talking about has led to … so i guess you could still make money if your good at it, but its not like it used to be ..
Realistic as in possible? Sure.
Realistic as in likely? No.
It seems like a hassle but some people have automated the task.
