Buy pallets or individual units of Costco customer returns and liquidated merchandise through the B-Stock auction platform, researching resale value on Facebook Marketplace or comparable retail listings before bidding, then resell the items individually online, through Facebook Marketplace for larger items or Whatnot live auctions for smaller consumable goods.
Chris Koerner challenges an experienced reseller, Shannon, to help him turn a starting bankroll into $10,000 profit in 10 days flat, buying returned and liquidated Costco merchandise through the B-Stock auction platform at pennies on the dollar (a $3,400 gazebo for $200, an $1,800 furniture set for $200) and reselling it on Facebook Marketplace and, for smaller items like food and drinks, through live-auction platforms like Whatnot.
Someone with storage space (a garage or a small storage unit) and access to a bit of starting capital, who's comfortable researching resale prices before bidding and willing to learn category-specific quirks like appliance grading and model research.
This same buy-liquidation-and-resell pattern shows up repeatedly across WAH creator content, sourcing returned or excess inventory well below retail and reselling it piece by piece, which is itself a signal that the underlying model genuinely works, not just a one-off story. What makes this version distinct: a Costco-specific sourcing angle through the B-Stock auction platform, a named experienced mentor walking through live bid research in real time, and the Whatnot live-auction resale channel for smaller consumable goods, a genuinely different selling mechanic than one-off Marketplace listings. Koerner is candid that categories like appliances and electronics require real category-specific knowledge to avoid getting burned, and that not every item resells quickly, sometimes you cut the price and take a loss just to free up storage space.
