Spaceport 83 - eBay Store

Spaceport 83 is an eBay storefront run out of Montgomery, Alabama, with 3,000+ items sold and a 100% positive feedback rating.

While the store's branding leans into a nostalgic 1980s theme - vintage computers, electronics, old movies, and books - postcards make up a substantial and well-organized part of the inventory. The store's Postcards section is broken out by "Postcards by Location," covering all 50 U.S. states individually, plus a general Postcards category and a separate Trade Cards category.

Card conditions and eras vary (chrome, vintage, unposted, and posted examples all appear across current listings), with typical single-card pricing in the high single digits. It's a good fit for collectors browsing state-specific postcard inventory from an active, highly-rated general seller rather than a postcard-only specialist.
