How much can I pack into the store before it bursts?

I tend to think I over order on a regular basis. But every once in a while I get a hint that maybe there is a method to my madness. 

Sabrina and Ashley have decided to takeover one of our book racks and create thematic displays. This removes space for about 20 books or so.

Just 20 books, but there is absolutely no place to put them. What's strange is that I get hundreds of books a week that I manage to find space for, but these 20 books seem to be a step too far. Which means, I think, that subconsciously I'm calibrating the flow of books to a fine degree. 

I've always felt that I have a spacial talent for figuring just by looking how much or how little product a space will hold. Along with an ability to make the most of the space we have. The joke in the store is that every week or so, at some point in the process, I'll look up from trying to find space and say, "That's it. There's no more space. We can't order anything more." To which Ash and Sabrina will roll their eyes. 

Funny thing is, it's been true for a long time, but it just keeps happening. The other joke is, "I've got to find a way to suspend books from the ceiling," to which Ash and Sabrina will usually agree and start brainstorming ways to do it. Ha.

 So I'm just going to say it. We're out of room. I got to quit ordering stuff....

My finger hovers over the order button. Nah....I'll figure it out...
