I ordered an Ott light from Joann's about 2 weeks ago during their 50% off sale. Then I get an email about a week later that it was canceled because it was out of stock. I was very disappointed, and may have to wait for them to go on sale again. I just bought a full spectrum natural light at Walmart for $20. Don't know if I like it or not, I don't have anything to compare it too??????
