Since the building still hasn’t been built out, let alone equipped, I say it’s at least sometime next year before it happens.
AA shirts can still be obtained, so if your local print shop can’t do it, find another shop. Do ask if it’s the USA-made AA or the Gildan-made AA blanks, though. If it’s the latter, then there’s no reason to pay an AA premium IMHO.
For this class of lighter weight ringspun shirts, Bella/Canvas also offers USA made shirts (3001u & 6004u for men/women), as does Royal Apparel (5051J & 5001) and Los Angeles Apparel (20001 & 21002).
If imported is fine, Next Level (3600 & 3300L) is a very good choice. Tultex can be a little cheaper, but for the class, they’re not as soft IMHO; likewise with Alstyle.
