I am sorry you had the fire that delayed being able to home things, which caused them to stay in the bag longer and likely causing the death of the animals. However having spoken with Christina the part of this that is not being told is that when you reported it to Paypal, after she agreed to refund, you tied her hands until paypal finished their investigation. So where you are saying she reniged on her promise to refund, you actually took her ability to refund away. In the end you got what you wanted with was a refund, be happy and go your seperate ways. I've never had a problem with Christina and will buy product from her again. I'm tired of seeing vendors getting abused and the whole story not being told.
When there was a problem with my last group buy and some of the items were either missing or doa, she readily replaced the doa items and missing items. Even the items that were doa because UPS dropped one of the boxes and crushed the box, breaking the styrofoam inside and popping several bags. That was not her fault, yet she replaced the items. There are always good and bad experiences with all vendors, even LFS (though I've not had any with our LFS personally).
