Tutorial for beginners

my vote would go to Phlearn. Their motto is they make learning Photoshop fun and they do for $8 per month and don't charge extra for the stock images used in the tutorials.

If you can afford classes, Melissa or someone with a similarly good reputation as a teacher would be better. The advantage of tuition is that the courses are structured and the teacher can judge how much you are taking in. If you use YouTube or even Lynda it is so easy to start at too advanced a level and be put off because you can't understand things. I must admit I agree with Trevor that Adobe TV is excellent and free-look up Russell Brown, Julianne Kost

You should also consider taking a class with an actual instructor if this is something you are going to be doing for a living. Beginner classes start at the beginning (at least, mine do).

As Dave says, Lynda.com is as good as it comes, but you have to pay to  subscribe.  Adobe TV is free, and not far off quality wise.  In fact the content is on a par, bu the Adobe TV tutorials are nowhere near as well structured.

Adobe TV does break it up into different levels of experience though, which might be just what you need.  Looking at the videos on this page, I'd be inclined to work through them in exactly the order they are displayed, as it looks like a sensible approach from what I can see of the titles.   Make sure you work along, and practice practice practice.   You don't need to learn it all at once, but you do need to reinforce each thing as you learn it, so concentrate on what is interesting, and directly relevant to what you want to use Photoshop for.

Good luck, and have fun, and please come back and ask questions if you get stuck.

HI

Take a look at Lynda.com. There are some excellent step by step tutorials there. I believe many of those same tutorials are now available via LinkedIn.
