AHRE (SC) - great customer service, fast shipping and nothing I've ordered smells fake or chemically
Peak Candle (CO) - I took advantage of some of their sampler pack sales. So far, everything I've soaped has worked out well.
Brambleberry - very good for both EO and FO
Camden Grey (FL) - I have had a very positive experience with them so far. I have bought primarily EOs from them. Their FOs are not as well reviewed as some other suppliers and I've only tried a few. Their prices are great. Shipping can be pricey unless you fall under 4 lbs and then it's flat rate fedex, $8.95
Elements Bath and Body (US South) - great customer service and fair prices. Quick and fairly priced shipping. While not all fragrances have been to my taste, they don't smell artificial or cheap.
SGS (US South): they have sniffie sampler packs - a sample perfume vial's worth x 5 for three dollars, including shipping. You can order up to three at a time. I haven't reordered yet, but OOB they smelled very promising.
I just ordered from Bitter Creek North (WI) for the first time.
I've also heard good things about Nature's Garden (midwest) and soapsupplies.net (FL) (flat rate $7.95 shipping) but haven't ordered from them.
