Here are a few items that stood out to me, with decent stock levels:
(I would recommend checking the intended fit and sizing guide, as I've noticed quite some variance between products.)
* Oxford Shirt - 100% Cotton : $20 (was $65) https://www.ascolour.com.au/mens-oxford-shirt-5401s/?sale
* Brush Crew Sweatshirt - 75% Cotton, 25% Polyester : $15 (was $52) https://www.ascolour.com.au/mens-brush-crew-5106/?sale
* Wafer Tee - 100% Cotton : $4 (was $26) https://www.ascolour.com.au/wos-wafer-tee-4002a/?sale
* Square Pocker Tee - 100% Cotton : $6 (was $25) https://www.ascolour.com.au/wos-square-pocket-tee-4046/?sale
When I went to check out, shipping options were $12 for standard and $18 for express. Edit: robotfrom1984 has mentioned that shipping is not flat rate and varies depending on how much you order.
