If you need to spend money, these sites sell interesting things:
Plum Party has quirky gifts for all occasions as well as everything you need for theme parties.
Archie McPhee, your pop culture superstore! We've spent lots of money at McPhee, and we feel good about it. If you need a gorilla suit, a rabbi boxing puppet, or radioactive gear, this is the place.
Galco’s Soda Pop Stop is an enormous soft drink warehouse based in Los Angeles. They stock an unbelievable array of obscure and small-manufacturer soft drinks, including nearly 60 varieties of cream soda. It isn't cheap (ever tried to ship lots of glass bottles full of liquid?), but if it's a soft drink, they can get it for you.
If you love candles as much as I do, check out Candlemart.com and the Arkansas Candle Company. The former supplied the vast majority of our wedding candles (remember all the candles?) at very good prices, and the latter we stumbled upon on our way across the country. We shopped at their warehouse outlet and bought lots of candles at pretty good prices. They have a great variety of scents and all candles are hand-poured.
We've gotten some very nice Celtic-themed stuff from Gryphon's Moon. If you want some really beautiful Celtic jewelry, though, check out Walker Metalsmiths. That's where we got our wedding rings.
Remember wax lips? Candy cigarettes? Want to have some? Here's where to look:
