62 oz plastic container of peanut M&M’s is $9.99 or $10.99 at Costco.
No peanut butter M&M’s. 
Wait till tomorrow.
Last time I bought the almond ones, then the day after the peanut butter hit the site.
It was a better deal last last time. $10.99 for 8 count of 9.3 oz bags.
This is what I get for getting my hopes up. $15.99 shipped from Costco.
Now I’m sad and still M&M less.
Edit: And now Woot! sold out of these. 
Wait till tomorrow, I’m guessing they’ll post more in gourmet because these are classy.
Costco often charges a higher price for delivery, especially for food items.
For select clothing items, they frequently offer $50 off of 10 items ordered online. Haven’t seen a similar deal for food items.
Saw these in my “Stuff you bought” and thought I’d add a remark about how this went with me.
These were inedible. I believe that the M&Ms been damaged by improper storage. The chocolate inside each “M” was chalky and white.
I got a full refund and I threw away 99.9% of these. Was a real bummer, the MEGA versions are hard to find locally.
