Yup, I've tried a couple of the "bargain" suppliers and haven't been very impressed so far. The FOs may be cheaper per ounce but if you end up using more because they're weaker or (even worse) you end up with a lovely batch of unscented soap because they fade to nothing during the cure, it's not such a bargain. Daystar is my favorite so far, both for the quality of the FOs and for the customer service.
