Idk what I would do if I were you LOOPY.
I would feel very guilty throwing out corals, but I just would not let them sell a frag for $40 that they received for free. They should give you something. That is so greedy and selfish of them. But then it would also be selfish of you to throw them out when you know they would take it.
That's a hard decision. If I had a choice, I wouldn't shop there anymore. I'm guessing you don't have much of a choice though, since you drive 1 hr to get there.
I would have been willing to buy some kenyas if I hadn't already bought a frag from C-list. Try selling them there, it shouldn't be hard. Or try the BAY. Just sell for 5$ and let them pay shipping.
I think you should try talking to the owner/manager. Explain to them your situation. You have frags that you are willing to give them, and you know they will make a serious profit. Tell them to give you $5-10 per frag in credit. They can sell it for up to $40, an 800% profit. At the same time, you will use that credit, and likely spend more than the credit is worth.
Or you can tell the manager you can take your frags elsewhere. Any business owner will see that it would be pretty silly not to agree.
You can even give him a "sample" and tell him to see how much he can make.
And I would give him extra if he does agree to do it with you, just to keep a good rapport.
