Yay Lark!
i am so glad to hear that you ordered a set! i am also glad that you mentioned that some listed are the book only. Sometimes, the sets and or decks are in better condition than how they are listed i have found. (Of course on rare occasions the reverse is also true. :<( But if i have any doubts i write to the marketplace seller and ask some questions. The set i bought was listed only as "good"! But the book, as i mentioned, is like new, and the cards still shrink wrapped.
Also, if an item is listed at a high price, lets take the "Greenwood Tarot" as an example, sometimes the sellers are negotiable about lowering the price a bit. (Especially if it has been listed for a long time.) i got my Greenwood set that way for 50 dollars off the asking price. Okay, so i still paid 250.00 USD for it. eek! But it was in pristine condition. Lol! i was so tired of losing it time after time on eBay....
