This customer ordered the same product (Serum 30 ml) today at 21:12 in order #1042.
Delivery history: see how many parcels reached the customer. You can also show how often a product is returned. These figures alone do not put an order on hold.
Your rules: choose which checks to use for each store. You can change the limits, such as how many past returns trigger a review.
You pay shipping fees, wait for stock to return and spend time checking orders.
