If you think you can make an avy bag for $20 then go for it!!! I don't think you are taking all the research & development, salaries, testing, marketing, etc, etc, etc...... into consideration when you are claiming these bags to have overly inflated profit margins. Also, welcome to capitalism. Again, if you think you can make an avy bag cheaper, do it and then make sure you sell it for the exact cost of the manufacturing so that people can't get mad at you for making a profit on your work and ideas. It might be even better if you just considered all the work and time a gift to the human race and just gave them away.
