October is almost over, and your shopping list isn't complete. Don't waste cash (or time) at specialty retailers. You won't find our favorite bargains in these stores. Instead, we prefer Costco's bulk buys and Kirkland generics.

If you're a fan of the warehouse club, we can help you unlock the true value of your Costco membership and save money on everything from cute boots to a massive pumpkin pie.

Our favorites won't be on store shelves for long, so don't delay grabbing these deals.
