Just came across these 3 packs of Polo Ralph Lauren trunks for $29 (normally a ridiculous $99). 20% off in cart reduces to $23.20. $10 shipping, but if you have a David Jones card that becomes free. Add in 8% Cashrewards and this ends up $21.35 (or $31.35 with shipping). Still a third of the retail price even with shipping. Enjoy!
A few different styles and colours, but not many sizes left (S, M, XL) depending on style:

Any deals on CK underwear? I like that CK fits tight and loose at the same time, gives the boys room to breath.
