Enjoy ALL your UPGRADES and NEW LINES OF SERVICE without a mail in rebate. …The company is getting rid of those mail-in rebates on its phones and other devices. It kicked off this SUNDAY. Best Buy and Radio Shack have been doing this for some time now. A Sprint spokesperson confirmed to BMS that customers will get instant rebates at its company owned stores. They didn’t give us an end date so you can expect Verizon, and AT&T to do the same thing soon (competition). I won’t be going anywhere.
