   "q": "Is postage included?",
   "a": "Not in the item prices. Every piece mails First-Class, and postage is quoted with the job at the USPS rate for your mail. For an estimate, tick the postage line under the total: presorted First-Class at $0.74 a piece, added at cost with no markup; USPS postage is $0.69 to $0.82 a piece. The prices on this page cover the form, the envelopes and processing your file."
  },
  {
   "q": "What is a pressure-seal notice?",
   "a": "A single sheet that is imaged, folded and sealed under pressure into its own mailer, so there is no envelope to stuff. The cohesive only bonds to itself, which makes the mailer tamper-evident."
  },
  {
   "q": "What does file processing cover?",
   "a": "Taking your invoice or notice file, building your brand onto a unique form, and the lasered impression on each double-sided page. It is charged once per pressure-seal notice and once per sheet of a letter."
  },
  {
   "q": "Why do you show your wholesale cost?",
   "a": "So you can see what each item costs at trade and what you pay. Your cost is the trade cost plus 25%, for processing your file, building your brand onto the form, proofing and mailing."
  },
  {
   "q": "How do I start?",
   "a": "Price it on this page, then get in touch through the contact page with your format and monthly volume. We take it from there."
