To understand, you gotta breakdown the costs of new and old; price per drawer is a good way I've been tracking.
People have been reporting brand new KRL or Epic costing them upfront on average $275/drawer, which is like 40-50% off of online price. The pricing is actually not really competitive to Lista (cost more than Lista), simply because some will argue that Lista is more superior product.
People have been reporting used KRL or Epic costing them on average $180-200/drawer. To break it down for used market:
The box: $2200
The top: $400(a guess)
The locker: $800 (a guess, but I've seen people asked ~$1k separately)
TOTAL: $3400 is a fair pricing, IMO.
