What is the difference between Walmart and K-Mart?

Why is alli not available? Walmart and Sam's have not had it in a couple of months and Kmart is out now?

• I had been taking Alli for the last 6 months or so. I usually would buy it at Sam's but in January they were out and have been out ever since. That time I found it at Walmart. The next time I needed it, Neither, Sam's, Walmart, or Kmart had it. Did they quit making it? I can't find any info.

• Answer:

  I have been looking at Walgreen's, along with Walmart and Sam's. I did find it available online but it was about $300 for the $50 bottle! I did find this on the Alli homepage: "GSK, the manufacturer of alli, is experiencing a supply shortage of the active ingredient used in alli. The alli team is working diligently to resolve the issue and apologize for any inconvenience this supply shortage may cause our consumers. Consumers should continue to adhere to the recommended diet and physical activity routine, which are the cornerstone of any weight loss program, and continue using alli once it is available."
