Note that we are trying some new supply chain stuff with our vendor. We used to order massive numbers of shirts all at once, which occasionally would lead to excess inventory; we also occasionally sold out of stuff and didn't notice it until people started emailing me. This time around we're placing smaller orders up front and taking advantage of automatic restocking on our vendor's part to keep the inventory refreshed when we run out of specific sizes. Hopefully that will prevent both having hundreds of extra shirts lying around, as well as never seeing stuff restocked when it sells out.
On the flipside, though, that means that these shirts might sell out relatively quickly, but if they do, they will hopefully be restocked within a week or so. So, in other words, don't panic if you don't get a shirt right away; check back in a few days and it'll probably be back in stock.
If you have any issues with your order, email firstname.lastname@example.org. If you have questions on our side, such as with your membership discount code or something similar, email email@example.com and we'll get you sorted out.
