Looking for alternative to MS Office

[gagaga]

I can't afford MS Office but i want a program that can do the same but is free or a lot cheaper.

I would use Word, Excel, Publisher and Access. What is available? Open Office is one but can i use that like Publisher too?

If you use MS stuff at work, it's always worth asking if they are part of the home use program - you get everything for about £12 quid postage ...
