www.riekesglass.com Great prices and customer service. I would call and get a hold of a rep. I don't think they come any larger than the two sizes though...
The best coffee scent IMO is JS Caramel Cinnamon Latte----wow, this is perfect. Very strong. Her Toffee Machiato is also really good, not very strong on the coffee, and the caramel is nice.
My personal favorite clean scent is citrus linen h20 from JS. It has the linen and the citrus, a perfect blend and the perfect strength. Not overpowering, but a very clean scent.
