Best Buy for IQbuds, page-302

Seeing as various posters are tracking various indicators - has anyone been recording IQbuds positioning on Best Buy's 'Best Selling' filter?

I intended to starting keeping tabs on it a week ago (check it once a day), but I've already missed a couple of days. Noticed something strange today though. Here's the full list:

31/5 - New stock arrived - #~125 out of 197 'wireless earbuds'
1/6 - In stock (2-8 day delay for store pickup) - Did not check
2/6 - In stock (12 day delay for store pickup) - #87 of 197
3/6 - In stock (free two day shipping) - #91
4/6 - In stock (US$20 discount, standard shipping) - #95
5/6 - In stock (No store pickup) - #98
6/6 - Out of stock (Available at El Camino Real) - Did not check
7/6 - Out of stock - #85

IQbuds jumped up 13 positions without any online stock, and only being available at the Ignore Store, where Nuheara ran the two day 'Try Before You Buy' campaign last week. My guess is either a faulty algorithm, or sales in that one physical store are going extremely well.
