Good Deal or Rip Off?

I need a few people's opinion about something. I make a living out of doing henna tattoos, sometimes for money, and sometimes as a favor. I don't live off it, but since it's something I like to do, I really don't mind buying the henna ink, and practicing how to draw.

Now, the henna ink itself, is really difficult to find. I only know one store that sells it, and it doesn't always have them on stock, so when I do go to the store (which is really far from where I live and I don't have a car), I'm always at chance that there will be or there won't be ink. Also, the ink itself, is really cheap, not in the good kind of cheap, and not really the best quality, but I manage since I can't find ink anywhere else.

I don't really like buying anything online, because I know that whatever I buy is going to cost me an arm or a leg for the shipping and handling, on top of the actual item itself, but I took a chance. I found a website that sells ink and other henna miscellaneous materials that can help out my practice.

On that website, I bought an 10 oz. bottle of pre-made henna ink (which is a lot), and a stencil book with 20 pages which has 80 pictures of stencils I can make with no problem. Both items came to a total of $84, plus the $12 of s&h, so in total it cost me $96.

I have never paid that much money for any ink before, but then again, I only buy a 2.5 oz. of ink at a store, and as far as stencils go, I usually just print pictures off the internet and make stencils out of them. Then again, I continue to buy ink when I can find it, and that's almost $20 every time I buy ink.

Did I get ripped off or did I get a good deal? Should I buy it again or should this be my last time buying ink online?
