I don't think it's anything personal. It may be 
as the other person said: to show you what 
they've offered and what they might offer in the 
future. You probably keep going back to those 
sites, after all, right? ^_~

My pet peeve is when dealers (pro or collectors) 
don't update to say that something's been sold. 
I'd probably buy a lot more if I wasn't wondering 
if the cel was there or not.
