Would someone clarify the relationship between St. Kilda (Glasgow), Gaelic Themes and Scottishtartanstore on eBay?

I bought a jacket and vest from Scottishtartanstore. They were very pleasant to do business with. When I got the package, the From address was St. Kilda, Glasgow. When I opened it, the label says Gaelic Themes.

Are these three one in the same?
