{"product_id":"u-s-postal-service","title":"U.S. Postal Service","description":"An NSA is a customized contract between USPS and a specific entity- often a mailer or foreign postal operator-typically lasting a year or more. NSAs provide customer-specific rates-generally lower prices on specific mail products-in exchange for meeting volume targets and mail preparation requirements. The goal of these agreements is generally to encourage additional mail volume and revenue. For example, an NSA may provide a postage rate discount, paid to the mailer as a rebate at the end of a fiscal year, for all mail volume above a specific threshold.","brand":"Createspace Independent Publishing Platform","offers":[{"title":"Default Title","offer_id":50020343021818,"sku":"9781503215160","price":15.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0840\/1253\/1962\/files\/imageloader_55933938-7fed-4d04-8c90-332cf4089fbf.jpg?v=1786136787","url":"https:\/\/mindsourcebooks.com\/products\/u-s-postal-service","provider":"Mind Source Books","version":"1.0","type":"link"}
