Just bought 2 sets of expedit-like shelves at costco. Never got any expedits because I would have to have them shipped (shipping is expensive for them) so it was cool to see these...they are only in 2x4 configuration, but are WAY heavier/sturdier than expedits. They only come in dark brown, and are $130...more expensive, but still cheaper than the shipping costs and as I mentioned, much sturdier...also dark brown is better than black/natural IMO. The cubes are 13x13x15. So if you don't live close to an Ikea like me, they are a proper alternative.
