I got a couple of duplicate playsets, the nursery and perfume palace. The nursery is nearly complete and since I know they are a pain to ship cost wise, I was wondering if trading for other common playsets would be better? Just paying postage. I already got these two and since I'm missing the other playsets, like the boutique, show stable, perm shop and dream castle. If I can't unload them I may just keep them at my dads. What are your thoughts?
