No more Costco bags...
I had a Costco bag for 2 1/2 years with no problems until recently when the wheels started sticking. Hard to drag a bag around literally for a week. Brought it back to Costco and they refunded my purchase price.
Went to the luggage aisle, and surprise! No more Costco Kirkland 22" bags! After several phone calls to several stores, the product has been discontinued and will no longer be sold. If you have some in your local store, buy 'em up and sell 'em on here!
Hope this helps.
