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.)
MENS:
* 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
WOMENS:
* 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.
Their clothes are great, especially from the sales section. However, shipping is quite pricey because the pricing will depend on how much you order rather than a flat fee. So the more you order, the more expensive shipping is.
