I bought mine at Walgreens. Couldn't beat the price for under $5.00. I wasn't that impressed with the product either really. I didn't notice any difference even after applying it nightly for about a month. Like others have said, it burned my eyes, so I would put it on at night, and in the morning my lashes felt all "crunchy" and the stuff would be all dried and flaking in the corners of my eyes. Maybe I was putting too much on? I guess I was going with the "more is better" theory... I too, like one of the other gals above, got a nasty cystic pimple on my eyebrow around the same time I was using it (that hasn't gone away to this day - over a year later....), so perhaps it was the product.
