The Costco in-warehouse Hot Buys weren't very interesting this month, so we've omitted them this time around. But you can always find the top Costco deals as voted by the Slickdeals community on this page (updated automatically 24/7).

As we previously mentioned, the Costco coupon book is now showcasing "everyday low price" items, indicated this time around with a green price followed by the words "your cost," as opposed to a dollar amount discount.

Don't forget that if you're a loyal Costco customer who spends at least $230 per month over the course of a year, it would benefit you to sign up for Costco's Executive Membership — the year-end reward certificate (2% back on purchases) basically pays for your membership fee.

Gain even more rewards with Citi's Costco Anywhere Visa Card, which offers an additional 2% cash back on all Costco purchases. Get more tips like these in our Costco Shopping Guide.

Thanks for this. I think I threw my coupon book out for this month. I just wish I knew the "MSRP" of some of these... hard to gauge whether some of them are worth it. I guess the coupons automatically apply anyway?

The chicken patties might be worth it. Perrier water is pretty good (has coupon now), but I think Pellegrino tastes better and has more of a carbonated kick to it.

This might be a dumb question - I just bought tires (haven't had them installed yet) - can I just cancel my order (return them) and wait till the 23rd to reorder and install them? I realize this is kind of a douche move, but I know Costco is really flexible with their returns and stuff and 60 bucks is 60 bucks... soo.. haha. Anyway, if anyone has had experience with this and can enlighten me, that would be much appreciated, thanks!
