The poor not effected 
Those Greedy kena 
Rich no need freebies to get scammed

That is a good summary.  The poor only buy essentials and may not even spend much time online to read these so-called "bargains".  
The wealthy will prefer to pay more from established online retailers.
The middle-classes may be more attracted to bargains offered by scammers online to stretch their dollar.
