SIZING
All of my blanks currently are Gildan 64000s. They're super soft and comfortable, and are medium weight (4.5 oz). They are also pre-shrunk, so they may fit a bit more snug than the average shirt. If you want a baggier fit, I would size up.

SHIPPING
My printers are located in the US, UK, and the EU. If you are in one of those countries, shipping should take anywhere from 5 days to 2 weeks. I know thats a big disparity, but most of the time it's pretty quick. However, if you really need something by a certain date, I would plan to order 2 weeks in advance.
If you are not located in one of those countries, shipping can take up to 30 days. I know, thats pretty bad. And I know what you're thinking: "What is this, 1890? Are they shipping this shit by horse and carriage? Is Arthur Morgan gonna hand deliver the stupid t-shirt that I bought on the internet?". Sadly, no. Arthur was busy being dead. Spoiler alert.
But in all seriousness, I think its cause they ship products in bulk to save on international fees, so they have to wait for orders to build up. In any event, I promise its worth it. The shirts are very nice.
