I went through this in May. The policy changed this spring. It's not supposed to involve buying your own boxes and MTS pays the postage. Must have had a bad CSR. Anyway the policy is still online but hard to find on their site now. I found it with Google.

I was sent one folded box the day after I cancelled and barely got everything in it, separated by bubble wrap. I called them about the absence of extra boxes for each piece of equipment and they said it would be OK. They payed the postage.
I guess there were no problems as I received my final month refund about 3 weeks later. But it's still a pretty lax procedure.
