How to make a card for sale post

Updated 2026-10-26

A good for sale post answers the buyer's first three questions before they DM you: what is it, what grade, how much.

On the image

• The slab, big and centered.
• The price, or "offers" if you want them.
• Your handle, so the image still points to you when it's shared or screenshotted.

In the caption

• Card name, year, set and number.
• Grader and grade.
• Price and whether it's firm.
• Payment methods and whether shipping is included.
• How to buy: comment, DM, or a link.

Keep it short

Long captions with every hashtag you can think of look like spam. Pick a handful of specific ones: the character, the set, the grader.

Multiple cards

Put up to three slabs in one image with a price under each, or post a carousel with one slab per image. Number them so buyers can say which one they want.

Make it in Grailshot

Grailshot has a For Sale layout: drop in the slab, type the price and your handle, and export. It writes a caption you can copy too.
