Hi, i bought tier 2 plan and so far i am really loving it. Just saw that you guys are launching the third tier and wanted to ask if it was possible to get tier 3 plan without buying a new tier? Or do we need to buy third tier separately? Also any discount or concession/offer for tier 2 users? It would be great if you could provide some offer for tier 2 users as at that time it was the highest tier.
