I'm planning my first trip to IKEA. I'm pretty sure I want to get the Expedit 4X4 bookcase. Should I call in advance to see if they have it? Also does anyone know how big the boxes are that this comes in? I was supposed to go with a friend who has an SUV but she had to postpone so I'm thinking of going on my own as I really want to start getting organized. I could potentially switch cars with DH who has an SUV if necessary. Any other tips for my first trip to IKEA? I'm planning on going during a weekday morning.
