One of the things I like about Amazon -- and one of the reasons I use it so much -- is that if I see something there I want but none are currently available I can put in a request to be sent a e-mail whenever a item comes up for sale. More then that, I can set in a max price -- and if the item is listed less then that, I'll buy it automaticaly with my CC.
Does EBay have anything like this? It would be great to put some items on a list and just be sent a e-mail when it pops up.
