But aside from mayo large enough to dress every sandwich in Manhattan, there's another (and more important) reason to flock to Costco -- Chanel and Louis Vuitton handbags!
The new location currently has Chanel Classic Flap handbags available for $1,999, though the salesperson, a man, was not sure what sizes were available (baby, small, medium, large or jumbo). These regularly sell anywhere from $1,795 to $2.495.
However, he did say that earlier today they sold out of Louis Vuitton Speedy bags, regularly priced from $665 to more than $3,000, all three going for $589 a pop. But there are currently "a lot" of Burberry and Coach bags, he said.
So, what else is in stock? Burberry's mini satchel for $1,019.99, Tod's medium shopper handbag for $549.99 and a Ferragamo "Marissa" handbag for $629.99.
Just getting access to these deals make the $50 membership fee seem like chump change.
Reps from Chanel and Louis Vuitton did not return calls for comment.
