My LFS used to give half cash value of what they'd give store credit. Which it isn't a lot to begin with. They don't do it anymore. Strictly store credit now, but it's definitely good to get supplies.Breeding pair of JD be fine in a 75. as would convicts. selling? may sell a few, your LFS may take some fry, but always as a credit. I trade my F1 jags for credit, and use to with my JD fry. so heaters, filters and the such cost my nothing per say, but as for cash in hand. naaa.
