The only ones I ever buy are yankee candle tarts and those glade (I think) glass jar ones with the pink love hearts on them. The yankee tarts are only £1 and I break a wee bit off and use them int he oil burners.....they last ages! I've bought all different scents in them and have had some lovely ones and some not so pleasant ones. I mainly like the pastel coloured ones and hate the food and xmas scented ones
My OH's friend sent him some soya melt (I think?) things for the oil burners aswell from Australia and I decided to first try out the cinnamon one first because it's xmas but I didn't like it. I've got quite a few left though but they're all fruit scents so I'm not sure if I'll like them.
