Out-of-Stock
Out-of-stock means a product is unavailable for purchase or fulfillment. In online grocery, out-of-stock issues are especially sensitive because customers often need exact products for planned meals, household routines, or weekly shopping.
Why it matters
Frequent out-of-stock problems can reduce trust, increase cancellations, and damage repeat purchase behavior. See grocery inventory management tips.
