Thought I'd replied to this a few days ago but that seems to have disappeared...
I'm looking at selling my Hive but it's in the UK so the shipping may be prohibitively expensive, and I don't think I'd be allowed to send the existing mealworms...then again they were shipped to me live so maybe I could?!?
From the brief look I've just had, and guessing at the weight, shipping would be between £60 and £80 depending on speed, and the going rate for 2nd hand Hives seems to be £250. If that shipping fee turns out to be correct I'd accept £300 but I'd want to weigh it to confirm, and check if I'm allowed to send the mealworms too.
Let me know if you're still interested.
