What products Costco sells right now?

Is there way to determine what's on sale on Costco(Kawasaki)? Rather than going there myself.

..I found this "Costco Member Limited Email Magazine". I'm guessing, for every week/month, they will send you free magazines which features what's on sale that week/month.
I'm a member, but before this, I want to know if there are other ways?

Thanks!

The mail magazine and actual mailers are the primary ways that they announce their sales. I don't think it's published online.

Mmm.. Is that so?

Alright, i'll sign up.
Thank you!

I'm a member, and I get a weekly email. However it usually relates to online purchases, and the actual store doesn't always have the same sales.
The pamphlet handed at the door or the booklet that has the tear out vouchers specific to discounts for that week seem to be the only way I know what is on sale.
