This is the best tanning product on the market by a long way.
Being someone who burns rather than tans, I can't get enough of this stuff.
I've bought it from the supermarket and Priceline, and the price has been comparable - cheap. I buy it in the lightest shade, but next time my bottle runs out I am going to try it in the next shade darker.
I exfoliate before I apply, then work in smallish sections. I use about 2-3 squirts per half-leg, working from the ankle upwards in long strokes. I wear a glove when I do it so I don't end up with brown palms. It goes on evenly with minimal care and doesn't streak. The colour isn't orange at all, just a nice bronze shade. Dries quickly and darkens slightly over the next few hours, but not enough to panic!
You can layer it if you want, but one coat is sufficient if you just want a light layer of colour.
If you don't live in Australia, I would be making a special effort to get your hands on this. It's seriously that good.
