Some online shops will hold periodic sales and/or 
drop prices on things that are slow to move. Some 
will not - their prices are what they are no 
matter what. But if the cel has been sitting 
there a decent amount of time (as in four or five 
months or more), you might consider writing to 
the dealer with an offer. It's best if you know 
that particular shop decently well, but even if 
you don't, it really doesn't hurt to ask.

Another thing is that some shops will allow a bit 
of a discount if you order a number of things at 
once - especially things that have been sitting 
there as opposed to something posted new - but 
this type of "bulk discount" (lack of a better 
term) usually is only accepted if your order is 
at least in the few hundred dollar range. . . 
Once again, it depends on the shop and the people 
running it.

Keep in mind also, the more expensive the cel, 
the more capital the dealer has tied up in it. If 
a dealer posts a $5000 Mononoke cel up on their 
site and no one buys it, that cel is basically 
$5000 of capital that they otherwise *could* be 
using to make more money (by using it to buy more 
cels to sell). The longer it sits there, the more 
the dealer "loses out". That is why many smaller 
dealers don't like risking bringing in the big 
ticket cels - if the cel sells they might make a 
nice profit, but if it doesn't, they could be in 
trouble.

One last thing you might want to keep in mind is 
what seems to be the particular store's markup. 
Many will mark up everything by a decently 
predictable amount. If you know the store well 
enough to guess that amount, you can 
approximately guess what they might have actually 
paid for the cel. (And thus, not undercut it - 
since a store can't resonably sell for less than 
aquisition costs.)
