Blog help needed- Formatting issues

Grr, I'm not happy with Blogger right now. My last post had so many formatting problems. I kept trying to edit, fix it, repost, over and over. It did not end well, as you can see below.

I've had this happen before and it drives me CRAZY!

I just want some consistency in my blog posts. But I don't want to retype everything that I post over and over (like the giveaway details).  I think that my cutting and pasting is what's messing up the formatting. I refuse to type every single thing each time I post a new giveaway though.

Here's what I need help with. What do you use to write your blog posts?

I've always done mine right in the Blogger provided compose window.  I've tried typing in Word and pasting here, but I do lose some formatting options that way. I might have to deal with that for now, though.

Are there any other options out there? Please share with me what you use.

Thanks in advance!
