Great choice of themes, but also a lot of items can be mixed and matched across themes so you can design your own theme. I've always found the items to be different and more "special" or more "unique" than other party stores. Sometimes you can find some of the unique items scattered across the other sites, but Party Ark is the only site I've seen with all the best designs in one place. They have a great eye for design. A few times, I've ordered at the last minute, and I've never had a problem getting my order before the day. The lady who runs it is also helpful, polite and friendly.
