Oh good grief.
I just compared the totals of two Build your own Bundles. If purchased today, the 11/19/2012 bundle is $8.98 instead of $17.95. A difference of $8.97.
The 11/29/2012 bundle is $13.14 instead of $22.29. A difference of $9.15.
For a total of $18.12.
I placed a request for a refund of the difference. It’s still within 30 days of the purchases and Black November doesn’t end till tonight. With the tendency for DAZ sales events to end prematurely, I placed that second order yesterday instead of today. Clearly ... I should have waited.
There may be a few other products I purchased during November that are further discounted, but these were the most obvious.
Edit: The Black November link (at least at the top of the Forum page) went to the Create Your Own Ultimate Holiday Bundle, and the build your bundle now button took me to the Black November Bundle product category. I didn’t try the links on the store page.
