Stock Reserver pro

When stock runs low, two shoppers can end up racing for the same item — and one of them ends up disappointed after paying for something you can't actually ship. Cart Reserve fixes this. The moment a shopper opens their cart, it quietly holds their items for a set number of minutes. If they complete checkout in time, the sale goes through as normal. If they don't, the hold releases automatically and the stock becomes available to others — no manual work, no oversold orders to apologize for.
