Hi Cass,
You might check out the Release Parties subforum...there are threads titled by month with all of the last year's worth of set reveals in there. Hope that helps a little! Happy shopping!
Along the side are the individual categories but I found it easiest to go by price of set and then I could see the entire sets and get an idea of how they were set up and what the sets entailed. BUT I must say, buying now- check out the new releases for the holidays! I am a circle and sentiment gal as well!
