...half the time, what I see on eBay I bid on 
from impulse (which is why I tend to stay away 
from eBay these days...I've never been truly "in 
debt", but it's put me pretty close...), so if 
someone I know really wants it, I let them have 
it. Of course, nowadays, I've found myself to be 
intensely lazy with eBay auctions...I don't like 
bidding if someone else has bid, and if someone 
outbids me I rarely make the effort to counter-
act. Heh ^^;;

However, even though I'll let someone have a YJ 
auction if it means more to them, if it's big 
enough to have moved me into using a deputy 
service (which I have used all of one time in my 
entire collecting career...for me, the 
whole "saving money" aspect is lost once a deputy 
service comes in...something that I would have 
bought at $30 I would not buy at the $50 it ends 
up being after a deputy service has gotten to it. 
It's stupid, I know, but I value my money, and 
plus, this helps keep impulse buying down :D), 
it's usually something really important to me. 
It's a bigger deal for me then, as well...but it 
all comes down to these factors:

1) Who saw it first? 

and...

2) Who wants it more? (i.e. is it wishlist, is it 
something they collect from, etc)

If I am the victor in both of those 
considerations, I don't back down. But, 
otherwise, I usually do, as I enjoy spreading joy 
moreso than hoarding it :D
