We don't hold a warehouse of stock - we make each batch to order, within whatever surplus we've actually been able to rescue. Right now, that means:

Presale boxes - our current batch, open for order ahead of production and shipped as soon as it's ready.
Subscription - our scheduled service, with two shipment dates a month, for anyone who wants Riff delivered on a regular cadence without reordering each time.
One-off orders - a limited number of standalone boxes each round, for anyone who'd rather order occasionally than subscribe.

Because we only produce within what's genuinely been rescued, availability moves batch to batch - that's by design, not a stock issue. Whichever way you order, we'll always tell you exactly when to expect your shipment.
