I have 5 lines (I am the primary line) one of my kids phones is available for upgrade 12/17. So I stop at my local Vzwireless store and ask if they can give me the instant rebate on 12/17 since I could just go to Costco wireless kiosk and get the instant rebate. He says no to the instant rebate but he can give me 10% off. So $279 with the $99 rebate in the mail... and tells me that costco has lousy customer service, etc. Now this kinda pisses me off since I have bought all my verizon wireless stuff (save 1 phone that was insurance replacement) from this guy/store and the best he does is 10%. So, my question is, if I buy from costco is there any reason to believe that they wouldn't be able to do the droid upgrade on my kids line and then transfer that phone (droid) to my line?
