What it was

Reselling was one of my favorite side hustles: sports cards, apparel, collectibles, and high-value flips on eBay, Whatnot, and whatever channel actually moved the item. Buy well, present well, sell well.

It worked. For a good year or two it was real part-time income — not a storefront brand, but a cash-flow muscle sitting next to the sports-collectible habit that never really left.

Timeline snapshot

  • Long before: Sports cards and flipping were already part of the story.
  • 2025: Named as Knup Resells and run seriously as a side hustle.
  • 2026: Wound down inventory and channels; kept the PC and Jordan collection.

Why it existed

I like owned inventory. Cards, gear, and apparel teach the same lesson domains do: taste plus patience plus a clean sale beats a complicated business model.

What it included

  1. Sports cards and collectibles
  2. Apparel and high-end clothing flips
  3. Random high-value items when the spread was real
  4. A part-time engine, never a full-time store to babysit

Where it is now

Retired. As we moved into a digital, nomad life, inventory and shipping stopped making sense. Sold pretty much everything — the cards, the apparel, the random objects. What stayed is the personal collection: PC cards, Jordan pieces, and the memorabilia I actually want to keep, not flip.
