Books, vinyl records, and media are some of the most reliable finds at yard sales. A first-edition hardcover bought for $1 can sell for $20 to $200+. Vinyl records from the right era and genre (original pressings, jazz, classic rock) regularly sell for $15 to $100. And USPS Media Mail makes shipping these items dirt cheap. But Media Mail has strict rules, and violating them can result in your package being opened, reclassified, and surcharged. Here is everything you need to know.
What Qualifies for Media Mail
USPS Media Mail is a special rate class for educational and media materials. It is dramatically cheaper than other services: a 3 lb package ships for roughly $4 to $5 via Media Mail versus $10 to $15 via Priority Mail. But not everything qualifies.
Eligible: Books (at least 8 pages, bound), music recordings (vinyl records, CDs), film (DVDs, Blu-ray of movies), sound recordings, educational reference charts, medical binders, scripts, and manuscripts.
Not eligible: Video games (this catches many new resellers), comic books with advertising, magazines, anything with advertising content, and any non-media items packed in the same box. USPS inspectors can and do open Media Mail packages. If they find a video game or a "thank you" card with your business name, you will be surcharged.
Packing Books to Prevent Damage
The most common book shipping damage is bent corners and cover scuffs. This happens when books move inside the mailer during sorting. The fix is simple: snug packaging.
- Wrap the book in a single sheet of kraft paper or tissue paper to protect the cover.
- Place in a properly sized book mailer or bubble mailer. The mailer should be snug, not loose. A book rattling in an oversized mailer will arrive with damaged corners.
- For hardcovers worth over $30, add a layer of cardboard stiffener on each side for extra protection.
🛒 Book Mailers, Adjustable Height, 25-Pack
Self-sealing book mailers that adjust to fit different book thicknesses. Stiff cardboard walls prevent bending and corner damage. The right mailer is worth more than extra bubble wrap.

Packing Vinyl Records: The Non-Negotiable Method
Records are fragile, valuable, and extremely unforgiving of bad packing. A single cracked record is a full refund and a one-star review. Here is the method used by Discogs sellers who ship thousands of records per year:
- Remove the record from the jacket. Place it in a new poly-lined inner sleeve and pack it outside the jacket. This prevents seam splits (the #1 record shipping damage).
- Place the jacket in a resealable outer sleeve.
- Sandwich the record and jacket between two cardboard stiffeners slightly larger than the record.
- Place in a purpose-built LP mailer. These are corrugated boxes designed for 12-inch records. Do not use a flat mailer or poly mailer for vinyl.

Bundles and Sets
For book bundles (3+ books) and record lots, switch from mailers to boxes. Stack books spine-down (not flat) to prevent warping, and fill any remaining space with crumpled kraft paper. For records, stack vertically (never flat) with cardboard dividers every 3 to 5 records. Records stacked flat can warp under their own weight during transit.
Media Mail Shipping Times
Media Mail is slow. USPS estimates 2 to 8 business days, but in practice it can take 10 to 14 days during peak periods. Always set buyer expectations in your listing description: "Ships via USPS Media Mail (2-8 business days)." Most buyers are fine with the wait when they understand it is a standard class of mail, not a delay on your end.
When to Skip Media Mail
For lightweight single books (under 1 lb), compare Media Mail to USPS Ground Advantage. The price difference is sometimes only $1 to $2, and Ground Advantage is significantly faster. For a $50 book, the faster shipping can justify the small extra cost in buyer satisfaction. For heavy lots (5+ lbs), Media Mail savings become substantial and are always worth using.
"Do Not Bend" Stickers
Cheap insurance. Slap a "Do Not Bend" sticker on book and record mailers. Does it guarantee gentle handling? No. But it helps, and at 2 cents per sticker it is the cheapest protection you can add.
🛒 Do Not Bend Stickers, 2x3in, 500-Pack
Bright red and white, impossible to miss. Apply to book mailers, record mailers, and any flat package containing artwork or photos. 500 stickers for under $8.
