I've noticed that sometimes merchants seem to disappear without warning from the dropdown menus.

A couple of weeks ago, I got a MyPoints email about a service, but when I went later on to look for it on the drop downs, it wasn't there. I sent an email to their customer service through the click through link and they responded that this merchant wasn't a partner, sorry for the inconvenience. Yesterday, I received another MyPoints email from the same merchant they said wasn't partnered.

Weirdness.

I'm guessing it's a glitch on the MyPoints side.
