Difficulty Ordering

We've been trying to order fragrance tins for the candle warmers at the gift shop. She finally called them to find out what was wrong. It turns out that the website says to order in increments of six. But what it really wanted was for the total to be divisible by twelve. You'd have a fifty-fifty chance of that with increments of six of each type. But in addition, they wanted four of each kind although it said six. So we got our order placed, but Melody had to figure to make sure the total was divisible by twelve. If they want to make ordering difficult, they've done it.
