So I recently bought a complete Lovecraft collection, but after opening a different collection in a bookstore I completely fell in love with it. Mine is one big volume, while the other comes in two volumes. I'd like to exchange mine for the two instead of buying them outright. There aren't many options for direct book swapping online. Should I try used bookstores? Lovecraft communities? Would it be seen as advertising or spam? (I'm not in America at the moment, but I will be soon and I have an address there.)
