I don't often get such emails/help what have you, 
mostly because I don't have a wishlist up.

Except for one person! :-)

There are more examples, but this is my favorite.

When you're suffering visual/auditory meltdown 
from too much stimulus at a con, your feet hurt, 
and you're not likely to notice anything less 
than a weapon going off near your head, it's ever 
so nice to have your best bud turn to you and 
say "here.  you should buy it."
