I would never, ever pass on a cel I knew I wanted 
just because another cel *might* come up later.  
Doubly so if I wasn't likely to be around when and 
if this other cel was offered.  If I held back 
like that I would never get any cels at all, 
'cause there's always a chance that something 
better will appear.

If you *really* like the cels, buy them now, and 
don't worry about what might or might not happen 
next week. Saving money and passing on cels 
because you *know* something else is coming up 
soon -- well, that's one thing.  If you risk 
waiting on an unknown, though, you might end up 
with none of the cels at all.

Of course, maybe that's just me.  ^_^
