Why Shop With Us

A small shop with a real track record

Grown Up Kids is a one-person toy and collectibles shop — a proud Native American and LGBT owned business. This website is new (we opened it in March 2026), but the shop behind it isn't: the same person, the same packing table, and the same standards have been selling to collectors on eBay for years.

How we run it

Honest quantities. We buy wide, not deep — most items are one-of-one. When we say there's only one left, that's not a sales tactic; it's the truth.
Fair prices. Every item is priced against real market sales of the exact same item. If you find it cheaper elsewhere, message us — we'd genuinely love to take a look.
Simple shipping. Flat $6 shipping anywhere in the US, and free on orders over $75.
Real help if something's off. If you receive your item and there is an issue, please feel free to reach out to us, as we would love to correct the situation.

Shop in person

Our glass cases are at Nerding Out in Inver Grove Heights, Minnesota. The case favorites — the things that sell best in person — are our 3D-printed pieces, sealed trading card booster packs and decks, and squishy toys, alongside single cards, figures and collectibles that never make it online. We're usually there Wednesdays, Fridays and Saturdays, and new stock lands every week.
