Where to buy office 365?

To purchase/resell office365 to customers is it better to purchase through Microsoft, Pax8, or somewhere else?
The pricing through Microsoft is basically the same as PAX8. Unless I’m missing something.

We use Ingram. The highest margins so far for us (in Switzerland).

If you go with Ingram just keep in mind their support is not that good. We go directly to MS for support.

Check out this site. They resale license from companies that sell them off for whatever reason.
