When setting up a Cart, you are asked only for "product id" and "quantity".What happens if we make a list of carts, but the product prices go up in the mean time?
Does the list get updated, or does it only take the price at the time of creation?
There is no mention of price in this system, which means the product prices (per created Cart) will change as you change product prices in your admin area. In other words, when a shopper adds to cart, prices are charged at the going rate, not at a historical rate.
