-personal preference
-if the person wishes to charge more and doesn't want his original prices referenced
-if the person doesn't want an active record of the sales progression of prices so that his prices aren't questioned against them
-if the person wants to have his sale prices kept non-public from anyone in his life that might be checking for sale prices/monies earned (at least, a non-bank/government entity since paypal would have record of it, unless they dealt only in money orders)
-If the person had issues with personal information being online and felt that money earned through sales was part of that personal information
-If the person was covering for the buyer who wished to potentially sell it at a higher price later on and not have the sale reference (buyer seller confidentiality)
