Priority Drop

Let shoppers pay for first access to your sold-out products, reserved for them when you restock.

Paid priority queue. Shoppers buy a priority pass in your normal Shopify checkout when a variant is sold out.
Reserved on restock. Restocked units are held for pass holders in the order they paid, and Shopify emails them.
Automatic refunds. No restock within your window? The fee is refunded in full, automatically.
