Another dead one this evening. Also have noted that one of the fish is smaller than the others and trying to steer clear of the others and they seem to be hassling him a bit. I fear that this one is next, I don't have another tank to move him too. I do have a small tank in the garage but this is not cycled.

1. Bad quality stock (as Fishlady has said) 2. LFS standard of care 3. Stress of transportation (think we can eliminate this as you have done you best to make it as stress free as possible) 4. Bad quality water in your tank (again eliminate this as your readings seem fine) 5. Other tank mates
As far as other tank mates are concerned do you have any other fish in the tank with the guppies? Have you noticed any possible fighting/bullying between the guppies themselves? Only guppies in the tank and I have not noticed any bullying.
As for the top two, what kind of rapport do you have with the LFS you bought them from?
The only reason I ask is you could speak to them and see if they have any had any issues. Other customers may have had problems or the LFS themselves may have lost some stock and if so I bet you they won't hesitate to speak to their supplier to complain. I could give them a call and mention it.
I think it's good business practice that a LFS should quarantine incoming stock before selling them onto customers as bad quality stock will tarnish their name and possibly lose them custom. However whether all LFS's do this is another thing. I bought them from Maidenhead Aquatics so I would imagine they have pretty high standards.

TOTAL HARDNESS 320 mg/l
Degrees German 18
I think it's 320, ill confirm tank readings with liquid test kit.
