The big Essentrics/Classical Stretch sale is my favorite. I don't always buy, but I do always watch for it each year.
The Bellicon sale fascinates me, too, though I never cave (no room for it and too spendy).
A Pure Barre sale would be nice with all the great releases this past year.
I hope UGI will discount their products again for the holidays. After buying the Zip Trainer system for $20, it's hard to justify spending $150-$200 for a heavier UGI ball ... but maybe I can justify this with a Black Friday discount.
And I hope Tracie Long's new 30-minute workouts will be available by then, too, sale or not.
