What if my franchisor force me to buy overpriced product(more than
double than local supplier)?  
I am currently running a franchise store at Colleyville,TX.

After being ripped off by an auto repair franchise, I did some
research that convinced me that they are generally a pyramid-type
investment. As a franchisee, you now have a significant overhead not
borne by independents. If the home office only provides inventory at
inflated prices, fails to resolve customer complaints, and simply
rents you a name and logo, what can you honestly offer to your
customers?
