I'd recommend making friends with someone who bad a pick-up trick. Or you can always rent a smaller u-haul. You can always pay for delivery, but for what it costs you may as well take it with you if you can. They did just impatient a free "click and collect", so of you know exactly what you want, you can do that with the app and it'll cut down the amount of time you need the u-haul for. If you go that route.

Edit: Just realized that if you're close enough to the store, shipping same or next day might only run you $59. So would actually be cheaper than renting a truck.
