Historic Price Shopper: Amazon Price Tracking

Adds Amazon.com historical price graph above the 'Add To Cart' button so you can monitor if it's a good time to buy.

Adds a graph of the price history above the "Add to Cart" button in Amazon. Clicking the minipic will load a larger chart on the screen. Clicking the larger chart will take you to camelcamelcamel.com where you can setup email or twitter alerts to monitor when the product reaches trigger prices that you specify. This only works on Amazon US, CA and UK websites. Update 0.50: Update to latest Chrome Manifest v3. Add Canadian Amazon. Update 0.27: Fix FakeSpot integration. Update 0.26: Add graph for movie rental/purchases Update 0.25: If no Amazon price graph available, shows 3rd party graph Update 0.21: Fix max-width issue on certain product pages.
