When you place an order with free shipping, any additional orders placed within the next 24 hours also qualify to get free shipping regardless of the amount. Since this second order was also over $25 (meaning the courtesy free shipping wasn't needed), did they somehow grant the courtesy credit in regards to the additional order free shipping??
This second order this morning has a $7 item I could get at Ace, but my Ace stores are both at least 20 miles away and I don't plan on going back to town before next week when this order should arrive.
