hi Evan,
I think the easiest way may be to call the Costco stores around your area and ask if they have item#966661 which is the item number for the 11' Parisol Umbrella. You can find the Costco locations and phone number on Costco's website:

I think Costco has started clearing out the patio/outdoor stuff so supplies may be limited.
Hope this helps,
Olli
