Interesting. Usually these are used instead of simple bus wire runs when having to use auto insertion machinery, not for hobby use. But I did a quick search on 28 gauge tinned copper bus wire and couldn't find any cheaper per foot (assuming a 2.5" resister length) then your purchase price! Of course you are limited to the pre-cut lengths of the 0 ohm resistors, where with bus wire you can use any length you require to bridge two points.
So what was your reasoning for purchasing those, just couldn't pass up a bargain?
