How often does Math Mammoth have a sale

[drjuliadc]

The first time I looked to buy anything from Math Mammoth was when they recently had a sale. The end date of the sale changed once or twice as I looked at it and I wondered if it was a long running sale or not. Now that the sale is over, it was obviously not a long running sale. Haha. 

It isn't anything I need right away, which is why I didn’t jump right on it. For future reference, I was wondering if any of you know how often she has a sale?

There are frequently 25% off sales, probably every couple of months.  The big 50% off complete set sale through hsbc is only once per year.

Homeschool buyers coop have usually had the full curriculum PDFs on sale around the start of the new school year every year.  I know they changed hands so maybe they will change but it is usually a really good deal
