My mom sells halloween costumes in her store. She has situations almost each Friday/Saturday where websites "guaranteed" delivery by that day and won't be delivering a costume at all. You're going to need to buy in person at this point. I wouldn't take a chance. The most they will compensate you with is a coupon for a % off for next year, good off certain dates, that locks you in a business you don't want to partner with. What you're going to get is a lot of worry. Like I said, buy in person.
