Whole Foods - their deals are up for 11/11 - 11/17.
Go to their website to find your local sales! At the top of the page put in your zip code and make whatever store you go to "your store". Then, click on "specials".
I will also say that both Whole Foods and Trader Joe's had pineapple for $2.99 when I went this past Monday! The one I got smells so good. I'll probably cut ours up tomorrow for a great treat!
