I tried to order these on sept. 7 for an event on sept 22, with 3-5 day shipping. A week later i check on line and it says they won't even ship until Oct. 10. Customer service from the seller was no help. Customer service from Amazon has the literacy level and problem solving skills of a second grader. #amateur hour #FAIL
