I hate trying to shove everything I buy at IKEA into my small car. All those flat packs just don’t fit in a small hatch back. If IKEA was closer, i could make several trips, but no, jam the car full, strap things to the roof, and figure the next time, I may have a different car.
Otherwise, flat packs have their uses, I couldn’t fit three billi shelves in my car otherwise.
