Apple price adjustment policy

I bought a MacBook Air at a store in New York last week and since they just dropped the price a few days ago I was looking into Apple's price correction policy, it states the following:

Apple reserves the right to change prices for products displayed at the Apple Store at any time, and to correct pricing errors that may inadvertently occur. Additional information about pricing and sales tax is available on the Payment & Pricing page. In the event you have been charged more than the posted price for a product in an Apple Retail Store, please see a Manager for a refund of the overcharge.

Should Apple reduce its price on any Apple-branded product within 14 calendar days from the date you receive your product, feel free to visit an Apple Retail Store or contact the Apple Contact Center at 1-800-676-2775 to request a refund or credit of the difference between the price you were charged and the current selling price. To receive the refund or credit you must contact Apple within 14 calendar days of the price change. Please note that this excludes limited-time price reductions, such as those that occur during special sales events, such as Black Friday or Cyber Monday.

So I called the number listed, but they told me the only way to get a price adjustment is to visit the store again. I'm travelling in Europe at the moment so thats not an option for me. Nowhere on the website can I find this policy, that you have to get a price adjustment in person. Hope someone can help me with this!
