Imported Lagers

I have tried to find a site of local retail shops that sell the Thailand beer, Singha. I haven’t been able to find anything other than one distributor called Glatzkeys or something like that, but they only sell to bars and restaurants with a liquor license. I would like to buy it by retail, like a 6- or 12-pack. Does anyone know if it is available in Columbus, Ohio, or anywhere in Ohio for that matter? Khap khun khrub.
