Treo 300

I went to the sprint department store earlier and i wanted the palm treo pro BUT it would cost me about $300 out the door (my upgrade covers 150 the underived price for the phone is $500). i got really confused because when i looked on the tag with the phone it said that it costs $199.99. THEN my cousin explained to me that the earnest price was in the small print, which included something called instan savings and a mail in rebate. now i cant get the phone i want. can someone legitimatize to me how this process works?? if the real price is about $500 then why do they have it in bold for $199.99?? what is this whole instant savings and letters in rebate stuff? thanks! (:

I bought a Palm T/X not too extended ago, and now I don't even see them in stores anymore. It seems that Palm is putting their emphasis on their phones such as the Treo, Centro and the upcoming Pre. I'm still happy with my around phone, so there is no reason for me to buy a new one. But, I'm worried that support for the Palm PDA's will dry up and that I will be stuck with a $300 paper weight.

Okay, so basically I yearn for to get the Blackberry Curve 8330 for Sprint. I have compiled a list of things I could sell on craigslist, or I could occupation my phone for it on craigslist but I am not getting any replies, I have the palm treo 800w its more expensive than the curve.

List:
Palm Treo 800w
32" inch Equal-angled CRT TV not hd its a sony trinitron
Laptop that is nearly brand new, dont really want to sell.
Guitar male lead 3 for pc
guitar her aurosmith for pc
guitar hero 3 with guitar for pc
Far Cry 2
Crysis
A laptop that is new, but the screen is broken and some of the keys on the keyboard are gone. It is genuine for gaming, but you just have to plug in a new screen.

Any ideas or ways I could get the curve, its about $300 on craigslist. What could I sales-clerk? And for how much
