Welcome, Lori!
You can usually find lots of oils/fats around town if you don't want to commit to buying in bulk just yet:
Coconut oil- can be found at Walmart, Asian markets, and even some grocery stores down the baking aisle.
Castor oil - can be found in 32 oz bottles at places like WholeFoods Mkt., Sprouts, and also some health food stores.
Lard- grocery stores, Walmart
Palm oil- Spectrum brand at WholeFoods Mkt., Sprouts, some grocery stores, Asian markets
Olive Oil- Costco, Sam's Club
High Oleic Sunflower oil- WholeFoods Mkt.
For quality FOs and EOs I would order online. There are many wonderful online vendors who cater to handmade soapmakers. I like to use these suppliers:
Peaks
Daystar
Nature's Garden
Oregon Trails
SweetCakes
TheScentWorks
WholeSaleSuppliesPlus
MajesticMountainSage
There are lots of other trustworty suppliers too, but these are the ones I use the most. Hopefully more will chime in.
