I'm very successful. Mainly because I'm not greedy. Some of these people are so unrealistic about what they should get. Once you've used it, it's a USED product. Not new; don't expect a new item price. When I sell, 90% of the time it's at least a 30-40% discount off what I paid.
And stop ripping people off for shipping. There's not much reason for charging more than $5 or $6 for a single scent's shipping.
Now. That's off my chest.
