I was going to say the same thing. I may not follow the instructions completely, but I now always inventory/identify ever part before I start putting something together. I got burned once building a stand alone, multi-level shelf system for Mrs Duke. I was on the last shelf when I realized I was short one set of hardware. I couldn't take it back since it was 80% built, and I didn't like my chances of getting a new set from the manufacturer in whatever country it was made. I wound up taking the remaining set (of two required) to a local hardware store where I eventually was able to put together the screws/washers/nuts I needed. Wasn't expensive, but it was time consuming.
