With the current logic, a customer can keep items in their shopping cart for any period of time, and whenever they choose to complete the checkout process there is absolutely zero validation done to ensure the price hasn’t changed. These price discrepancies can occur through many scenarios (ie. Items left in cart for extended time frames, not completing a purchase while a promotion or sale is active, etc). I can’t think of any e-commerce platform or company that doesn’t perform some type of pricing validation or refresh (up or down) to ensure that every time an order is placed the prices are real time. Just as the “pay for exact weight” functionality was a big draw for farms to use the graze cart platform because of the fairness to both the consumer and farmer, so too should be ensuring the customer is always charged accurately based on current pricing.
