Netherworld Postage greeting card ($0.13 Sale!) ($0.13 Sale!)

Is this really $0.13? (Yes, plus S&H, sales tax, etc.)


The card is available at $0.13, plus our normal shipping and handling, sales tax, and/or international fees charged by your country and/or your international postal service.

This card processes just like any other order, it's just very heavily discounted. If you order physical products in addition to this card, they will ship together at our normal speed.

You are not obligated to buy anything else, this is not a subscription, there is no catch.

This is literally just a sale designed to gain a lot of attention, have a bunch of fun, and promote Netherworld Post Office.

Okay, but... why?

We love Friday the 13th as a holiday, so every time it pops up on the calendar, we offer it for a weekend.

Also, we sometimes offer it to stress test a new system, because it has been too long since we've had a sale, or frankly, because the harmless chaos it creates is a lot of fun to handle.

What if I don't like it? (Spoiler: all sales are final)

Our store has an "all sales final" policy on all orders, including promotional offers such as this.

The mystery is intended to be part of the fun, but we can appreciate the uncertainty. If you're on the fence, have a look around the shop to get a sense of our style, humor, drama, etc.!

$0.13 cards are drawn, written, designed, and printed exactly like any of our other cards. It has simply been designated for sale for a weekend.

After the sale ends, this card will be designated "out of stock" until late May 2024. This gives us time to print and ship, then time for customers to receive and enjoy, their order. After this waiting period, this card will become a standard product at our normal price.

Netherworld Post Office offers free haunting and cursing services on all orders, so there is a chance this card may thus be affected. Hopefully to your benefit! Please consult the person, or thing, that gave you this card for specific details — we are bound to silence by the arcane rules of stationery purveyors, ghost post business etiquette, and mortal confidentiality laws.

Send mail! It is fun and inexpensive.

Wasn’t this a neat thing to receive? We have an ever growing group of rambles about who to mail (and tips on how to get started mailing) on our site.


Our greeting cards come with a blank eggshell-white envelope. The color is a gentle off-white, helping ensure your cards and letters will not get mixed up with junk mail, bills, or other undesirable postal bits.

Our card interiors are blank.

Both cards and envelopes are produced with uncoated paper, allowing for a smooth, even writing surface with most pens, pencils, markers, etc.

Printed in the USA.


When closed, greeting cards are 4.25 x 5.5 inches (about 10.8 x 13.3cm), which is the same size as a sheet of letter paper folded both horizontally and vertically.

Envelopes are 4.375 x 5.75 inches (about 11.1 x 14.6cm) and can comfortably fit a card and a few sheets of paper.

In stationery stores within the United States, this is commonly referred to as size "A2".

A card and envelope together weigh 0.5 ounces (about 14g).
