When you place an order at IKEA, everything gets shipped to a distributor in ABQ. The distributor will deliver to Marfa when they have at least 6 orders. It can take a while for these orders to stack up, which is why it sometimes takes up to three months to get your stuff.
I placed an order last week and called ABQ. Turns out, I'm order number 5 of 6, which means that truck is coming pretty soon. If you have been thinking about placing an order, now would be a great time to do it. You'd get your stuff pretty quickly and it would push up the delivery for orders 1-5. ABQ says they hope to send a truck by the end of October if they get enough orders to do so, etc.
