If you were remotely worried about buying frozen fish on the internet from these guys, don't be! I ordered some sushi salmon and tuna from these people. I had lots of queries as I needed to know how to handle the fish, given I was to be eating it raw. The staff were so, so helpful and reassuring. I ordered the fish which arrived next day - still beautifully frozen. They use DPD as their couriers who are also brilliant, as you are able to track the package very accurately. I've attached a photo of the sushi my son and I made today! In a nutshell, I am now a (very happy) customer of The Fish Society for life!
