PartyLite candle holders and decorations are rather expensive, so I wouldn't bother with them unless you are hosting a party and get the special offers. However the selection of fragrances available is phenominal. Unlike many companies you are able to buy your favourite scents in tea light size making them more affordable. I also find the the scents are so strong you can smell them even without lighting them. I leave them around the house, instead of using air fresheners, so when I come after a long day at work, the house smells lovely and comforting.
A word of advice: When you're going to a partlite party, set youself a maximum budget. That way you don't risk impulse buying and if you decide you want more, you can always host your own party and get the hostess discounts/freebies.
