Thai was much much later, but when Atlas/Seaboard was announced, I asked my regular candy store to make sure they carried them and was told what comes in, comes in.
When the first ones showed up, I pointed them out to the owner and he didn't care. I did ask him if he could reorder a book I missed and he said he would try but it never showed up.
He only carried DC, Marvel and Charlton until carrying Atlas for a few months. Interestingly, he did not get any of the last issues of the Atlas titles, so I guess the distributor bailed on them early.
