I use Nu-Scents oils and many of them are good. I believe they have a steep handling fee, so you may want to check that out before you order. I generally pick up and avoid the fee. Some of their scents are some of my best sellers (Fresh Apple, Vanilla Coconut, English Ivy, Cantaloupe Lily). I haven't had any customer service problems, though I wish they'd tell me when something is out of stock. I've only had two issues, and they've corrected both times. eta: If you need to contact them other than placing an order, I recommend a phone call over e-mail. Can be slow to respond via e-mail.
