Best Pleace to buy microsoft programs

[emanatlarge]

I failed to convert my access code for all my Microsoft programs so they stop running and I have to get a new access code I think

does any one know a good place to buy Microsoft programs for cheap?
Sorry if this is against the rules. If so delete.

cheapest you will find will be the academic edition which you will need provide proof that you are a faculty or student before purchasing.

OEM editions are also cheap but come with no warranty or tech support
