How it works

Buying

  1. Search by spec. Filter by club type, hand, flex, loft and condition.
  2. Check the fair-value range. Every listing shows what similar clubs sell for.
  3. Pay safely. Your money is held until you confirm the club matches the listing.

Selling

  1. List in minutes. Add photos and specs; we suggest a price.
  2. Ship with a prepaid label. Box it up and drop it off.
  3. Get paid. Funds release once the buyer confirms delivery.

Keep more of every sale

One flat 9% seller fee. No listing fees. Founding sellers pay 0% for their first 90 days.

Built to keep fakes out

Counterfeit clubs are sold almost entirely online. Every rule here exists so the club you buy is the club you paid for.

Serial-number checks

Required for drivers, woods, hybrids and putters, with close-up photos.

US sellers only

Every seller is identity-verified. No listings shipped from overseas.

Too-good-to-be-true flags

Prices far below fair value get a manual review before they go live.

Money held until it's right

Not as described or not genuine? Full refund, and the seller is removed.
