Ship & get paid

Pack it with care, ship it out, and your earnings are paid out automatically — minus our 5% commission.

Make listings that sell

A great listing is the difference between a quick sale and a stale one. A few habits go a long way.

Photos do the selling

Use natural light and show the actual item — not a stock photo. A short video from a few angles builds huge trust.

Be honest and specific

List dimensions, condition, materials, and any quirks. Accurate listings mean happy buyers and far fewer disputes.

Price it fairly

Factor in your time, material cost, and the 5% commission. Competitive, honest pricing wins repeat buyers.

Reply quickly

Fast, friendly answers turn browsers into buyers. Hobbyists love sellers who clearly know their stuff.

Packing & shipping

Careful packing is what separates great sellers from the rest. A well-protected package that arrives in perfect condition earns trust, repeat buyers, and glowing reviews.

  • Pack snugly so nothing shifts in transit — wrap fragile items like glass or printed decor in bubble wrap or foam.
  • For live plants, wrap the roots in a damp paper towel and seal them in a bag so they arrive hydrated.
  • Choose a sturdy box sized to the item, and fill empty space so the contents can't rattle around.
  • Always use a tracked service and share the tracking number with your buyer.
  • Ship promptly after a sale — fast dispatch is one of the biggest drivers of great reviews.
