I hope you managed to get rid of the coffee smell. It can linger for a long time. Or maybe it’s now the most aromatic silver ukulele ever! Was it a protest from you trying to feed your 4 year old coffee? Lol. In any case now it has a great story for you to tell when you show it off to others.If your disappointed now, you might be even more disgusted if you keep in over the log term or when you goto pass it on. Im not sure a discount would be appropriate, unless it was significant. Definitely, a return in my book. Whatever happens, please make sure you feel good about it....otherwise its best to just return it. as a side not, I have a KCM-25 I bought from a store in Hawaii. its a great instrument for the money. my 4 years old poured my coffee in the sound hole one morning..about a half a cup, but still going strong after a bit of TLC.
