Remove BestBuy API requirement, or make it optional?

[burvilc]

I get the following error when I go through the steps in the README and run start.sh. I got around this by setting products = "hello" instead of products = req.json()['products']. Since the goal here isn't to buy BestBuy products, can you make it an option to turn that if not desired?

I left the bestbuy API dependency in there out of sheer laziness... you’re right, I should definitely take this out. thanks for reminding me!
