What kind of fish are you trying to get? I don't recall having to condition water for exhorbitant time periods with your boring basic goldfish and guppies XD
Hell I don't even remember conditioning water at all, basically fill tank, let it stand for a day or so which gives you time to wash your gravel and plants and then decorate tank, and then go get fish and float them in the tank in their transport bags, then you open the transport bag and let in some tank water, float a bit more, then a bit more tank water, then put the mouth of the transport bag into the tank and let them swim out.
Only time my fish ever died was when they were suicidal and when I needed friends/housemates to look after them when I went home (uni students do stupid things like photograph fish in beer bottles apparently) XD
It's just a variety of guppies. The price sounds similar to yours except apparently to remove the heavy metals and chlorine from our tap water was have to add this stuff at the start then add other stuff for the next two days.
I want most pleased at the idea of my tap water having heavy metals in it!
I am hoping that the fish are hardy wee bastard when all this is over and they are in there!
HEAVY METAL? AWESOME! \m/
