Questions buyers ask
How do sample boxes work?
Check the coffee yourself before you bid: 150 g of green coffee from every lot in the auction, at US$180 per box with shipping included. Boxes are limited, so requests are served first come, first served, with a waitlist once they run out.
uncrack never takes payment. The auction's exporter (or presenter) sends your payment request through uncrack, and genuine links always start with uncrack.auction/pay/
Who ships the coffee to me?
Each winning bid settles directly with the origin’s official exporter, who ships your coffee. Shipping terms are agreed with the exporter.
Is there a minimum bid or lot size?
Both vary by auction. Every lot within an auction shares the same starting price, and you’ll see it on the lots once the auction opens. For the Honduras auctions, lots range from 15 kg up to around 120–130 kg.
Too much for a micro-roastery?Team up with other roasters and bid on a lot together. One roaster places bids on behalf of the group.
Can I cancel a bid?
No. Every bid you place goes through a confirmation. Once confirmed, it can’t be cancelled or changed. The one exception is an obvious error, such as a misplaced decimal point: tell the house before the auction closes, and it may cancel the bid if that is fair to other bidders.
