The drop off line up starts well before the staff officially open the donation drop off (9am last time I was there, about 3 weeks ago). I got there at 8:45am, and the queue had already snaked around the inner parking lot fronting the store. But once you get moving- when they begin letting cars in through the drive through to drop off their items into bins- it moves fairly quickly. I was impressed at how the staff coordinated the process and was happy to donate. Good luck!
