Where Can I buy Softwear T-Shirts from Microsoft?

They were just released today, but it seems that only a select number of retailers in major cities were included in the release. I went to the Microsoft page for Softwear and it doesn't give you any information pertaining to those retailers or anyway to order them. Anyway, does anyone know of a retailer website that has them listed for sale? Or by some slim chance is there a retailer near Central Ohio? I am looking for the MS DOS shirt as a Christmas gift.

Thanks!

ebay perhaps
