Try going to the front page of Rakuten, it shows “One Day Only 15% Off” and Wine.com is listed on the front page for me. Also, maybe make sure you’re logged in as well.
Not sure, mine was showing as 7.5% in the pop up/plug in this morning. I went ahead and activated it at 7.5% and it changed to 15%. Placed an order at 15% and now the pop up/plug in is showing as 15%.
T-Vine out of Calistoga has a President’s Day mixed case Sale with 35% off and $1 shipping for anything off their 2018 vintage. Apply code Mix at check out.
Huge fan of their Black Sears Vineyard Howell Mountain Zin and the '18 vintage is really good from what I have tasted.
WDC confession - if I have to add an inexpensive bottle to my order to get me over the minimum, I mentally (and in CT) apply the whole discount to the main bottle and consider myself to have overpaid on the cheap one.
