Where can I find Ideal Sweetener?

We’ve gotten a couple of coupons for free 50 ct package of Ideal sweetener, but I’m just now getting around to redeeming them and can’t find it at King Soopers.  Anyone know where you can find Ideal sweetener in Colorado Springs?

By the way, another coupon we frequently get free coupons for is for a free roll of Marcal Small Steps paper towels or toilet paper.  There’s been quite a bit of discussion about where to find the single rolls, and I think the consensus is that you can find them at the commissary, and Albertsons has carried them as well (right?).
