I have a Cherry Heart Lolly in my trades (had forgot about it til someone just made an offer lol) I'm unsure of the price to accept? I have been offered 250,000sp... should I be seeking more or less?

I'd say more - SubetaLodge estimates the price at a little over a million, and only one item from this set is below 250K.

I would ask for at least 1m, it's not an item that restocks and yours is the only one in trades.

thanks! I had a new offer of 1mil at some point yesterday so I think I'm gonna go ahead and accept that :)
