About Price markup detector

Sometimes you find a website where all the prices are "weird" (like $12.82) and you just know someone has applied a percentage markup to the normal prices. This extension (on the active tab - click only, it doesn't track you) will look at the prices and find the mathematically "best" explanation for this, or say it can't find one. Useful for your favorite delivery apps, especially.
