Personally, I don't think anyone should get upset if a fish dies and expect a refund if that is not a store's policy. I've witnessed fish eat at a store, visually inspected them, temp acclimated, drip acclimated for hours, provided a peaceful QT environment, basically did everything possible to ensure sucess and still had fish die. I was offered a 20% discount when my fish died IF I put the fish in a ziplock and froze it. Seeing how it was my first visit to the store, I understood why the owner didn't trust me and asked that the fish be frozen. He didn't know me and had no idea if I was trying to pull a scam on a really expensive fish. I don't blame the shop or the owner because the fish died. Nor do I blame anyone that the 2nd fish I bought had what looked like a very small scratch which developed into an open sore on it's body which got worse in QT until it also died. Sure, there is not a money-back guarantee but at least there might be a 20% discount to replace the fish. ( I flushed my dead fish before realizing I needed to freeze it to get 20% off the next one, so I'm S.O.L.)
Am I happy with the experience, no. Am I upset with RI, no. Does the policy make me want to only buy fish from places with a guarantee? Perhaps, but 20% off another fish is still better than the multitude of other stores that have no guarantee or discount whatsoever.
The last thing I'll say is that I never recieved any acknowledgement regarding my (3) requests for a replacement fish. I realize it can take a while for a specific fish to be available due to various factors outside of the supplier's control but I have no confirmation I'm even on a waiting list. So the ball is in their court as to wheher or not we'll be doing any more business together.
