I agree with @itiwhetu that how are you sure that stress caused the death of your fish.
I buy fish quite frequently from the lfs, and based on my observations, there are a few reasons why a new fish die:
1) The fish is carrying disease from the fish farm.
2) The fish is infected with disease while in the fish store.
3) High ammonia, nitrite during transportation from the farm to the fish store will weaken the fish. If your tank isn't cycled properly, it will kill them. Some lfs tanks will also have high ammonia if they keep too many fish in the tanks just like some of the lfs in my place.
4) Too much changes in the water chemistry(GH and pH) from the fish farm to the fish store and into your tank.
Though stress is bad, usually it's the disease, high ammonia/nitrite or drastic change in water chemistry that killed them(imo).
Visit the fish store again and observe the fish there for any signs/symptoms of disease. Some diseases can be deadly and hard to eradicate once they get into your tank.
Observe the Gudgeon fish tank and all other tanks. Sometimes the disease is spread from another tank in the fish shop especially when they used the same nets to catch all the fish or if the tanks are sharing the same filtration system.
If the fish is already infected, then don't buy from them at the moment. Wait for the next batch of fish.
Nevertheless, if their fish are healthy, then you can consider buying them again but it'll be better to diagnose and find out the reason of the death before buying again.
