There are a few interesting deals that are coming up during the 7 year anniversary, but the sellers are doing their usual thing (like the weeks leading up to 11:11) and have raised their current prices to make the price drop seem much better than what they really are.
For instance the store that is selling the Qian25 at a "discounted" price during the event, usually sell the same buds for an even lower regular price. So the buds are actually more expensive during the event.
The best way I know on how to keep track about this is by using the AliPrice plug-in. And if you don't want to install the plug-in, you can still use the search function at their site.

I think the best way to find good deals during the Ali events is by collecting Ali coupons.
For instance, I got the XDuoo X3, TY Hi-Z HP650 and TY Hi-Z HP320M for a total of $165 by using $35 in Ali and seller coupons, during last 11:11.
