A while ago I ordered a pond clear product and then took ill so I was not able to collect it. Today, several weeks later, i found they had still kept it for me. - That's service and loyalty.
I have had nothing but good advice form M&R (Dogfish). I used to have a lot of tropical fish (7 tanks) and bred them. I sold the babies back to the shop in exchange for fish food and other sundries, and always had a good relationship with them.
When I decided to concentrate on an outside pond they bought back my tropical fish and gave me pond fish food in exchange, which can be very expensive.
They also took baby orfe from me and gave me fish food in exchange.
Now I have uniquely Golden Rudd who survive very well in our climate and in almost any water condition. I get good advice on water treatment and they undercut the other nearby fish shop in fish food prices.
Give them loyalty and it is returned 110%. I love the shop and the staff, and would not go elsewhere. Especially the 'Old Man' - He knows what he is talking about and will give you good advice.
