They credit you up front. You have certain amount of time, think 15 days, to send in your trade. Your company will benefit from the trade in.
You would be better to sell the phone on swappa. I don't know what you have, but there was someone selling their note 10+ for $365 to some online place that buys phones. That option would be a quick sale. You probably get more on swappa, but will take longer and you have to deal with possible scams
Thanks. That's what I thought so I got mine through BestBuy.
