Need a cheap (or rather free) office pack…? Try out this free office pack and see if it that you can use. You don’t have to waste money on Microsoft Office. Go opensource. I have chosen to use mostly opensource and free (public domain) software and PHP-scripts. I buy software rarely these days. Can I find a free alternativ I go for it.
Still using WinRAR or WinZip…? Forget them. Download and use 7-Zip instead. Why…? It’s free and it does exstract both RAR and ZIP-files easy. And it can also make ZIP-files. So go for it. No need to throw away your money then you can get free alternatives on the net easy.
