Costco In-Warehouse Only: 180-Ct Kirkland Fast Acting Dairy Digestive Lactase Caplets $13 (Pricing/Availability Will Vary)

Costco has Kirkland Signature Fast Acting Lactase, 180 Caplets for $3 off until November 23, 2025. The online price is $19.99 - $3 = $16.99. But the in-warehouse price is $15.99 - $3 = $12.99. (Check the Costco app for availability at your local warehouse) Costco seems to have this $3 off promotion every so often but I never see it advertised in their savings book. So I'm just letting others know it's on sale right now, if they didn't know already.
