I don't think Costco sells a replacement tarp for these buildings. Inland does for $150.00. Go Look at both, and compare. I would not think they are the same. These are quite heavy.
I came from Langley just before they opened up Costco, now the closest is 1 1/2 hours away in Vernon. It's a small price to pay for quiet... peacful living... in a town where there are no traffic lights, and I can't go to town without seeing atleast 5 people I know, and saying hi and chatting for awhile.
Ohya,... Jason, Marty, and Todd have Zellers, in Salmon Arm....I'm in Sicamous 1/2 hour away , we have the Bargain Shop.
