Unadvertised savings at Costco

We all know about the 2-week coupon deals that come monthly or bi-monthly. We also know about the Passport to Savings, a summer's worth of coupons specified by week.

However, you will often find items that have an instant manufacturer's rebate or instant savings that is unadvertised. There's not really a place online where these are tracked that I know of. I think Costco does this intentionally to get foot traffic and people through the doors.

One deal that we found a few weeks ago was the Kirkland Signature Fish Oil Omega 3 Concentrate - 400 softgels (#926628), originally priced at $8.99, but with an instant savings of $2, it was $6.99. These are the "fishy" smelling pills, not the more expensive enteric-coated ones. But $6.99 for 400 softgels is a steal!

Another deal mined from Baby Cheapskate, Enfamil Lipil (powder) formula - 38oz can for $28 (regular price $32). Should be on sale for that price through August 28.

Another baby/vitamin-related note: Our doctor recommended supplementing our daughter with Enfamil brand Tri-Vi-Sol, a vitamin supplement for breastfed infants. There are 3 essential vitamins: A, C D. Breast milk is by far the best food for infants, but it apparently lacks recommended amounts of vitamin D. If you were to walk into your local drugstore, it would probably run $9.89 for the 1.67 fl. oz bottle. Walmart probably carries it for less, but it wasn't in stock at 2 Walmarts that we went to. Costco, of all places, has it for $8.59, which is the lowest I've seen. It's in the pharmacy section, on the counter at our Costco. There is probably a corresponding generic drug, but I haven't looked for it.
