Search tips

Use uncommon words For example, if you want to know the cost of a Priority Mail Flat Rate box, instead of searching for "Priority Mail" or "box," try searching for "Flat Rate" instead.
Use specific phrases The term "shipping label" will provide fewer returned FAQs than the word "label." Similarly the phrase "technical support" will return fewer results than "technical."
