They guppies came in and were in great shape. They were packed excellently and were not in distress when unpacked. Acclimation went well and they're doing great.
I only suggest that it be written in the about page or on the shipping confirmation that signature will be required. I'm not sure if its standard to ship with required signature but as a first time buyer I was under the impression that I did not have to meet the mailman for the package. Due to this, I had to track down my mailman and meet him later in his route, which caused me to go past the DOA guarantee's time limit. Luckily I did not need the guarantee, so there was no harm done.
