Can you promote in r/baseballcards?
Share baseball cards and collectibles, pulls, news, memorabilia, funny stories, cards for sale or trade, and absolutely no ebay auctions.
The short answer
If replying as a founder, be transparent about your affiliation, keep messages relevant/helpful, use the Sale/Trade flair or monthly thread, include required info (price, image), and avoid external links or overt advertisement.
What works here
- Posting cards for sale/trade using the sub's required format (price + image)
- Participating in discussions and answering questions
- Using the Sale/Trade flairs/threads for offers
What gets posts removed
- Linking to external shops/ebay/discord or posting outside sales links
- Unsolicited advertising, recruitment, or promotional posts outside allowed threads
- Posting sales without price/image or bypassing pinned post rules
Where this comes from

Rules explicitly ban eBay auctions and links to outside sales or advertisements.
Sales must follow pinned format
All 'for sale' posts must include a starting price within reality and an image; use the pinned post style.
Use filters/threads
The sub provides Sale and Trade filters/threads indicating where such posts belong.
No overt advertising
Sidebar encourages hobby posts and explicitly forbids outside sale links and advertising.
