i hate when i find things online and my size sells out before i can buy it. i bought the joggers online, but i'm looking for the jacket in a XL ideally, or L. they're online only. i see costco sells returns to auction, but i can't find who resells them. i've seen them on ebay at twice the price. any direction how or where i can find the jacket?
