Just stumbled upon this flash sale as I literally bought a few of these bundles last night. Sale has about 13 hours left. Normally around $23 for a 2 pack, but the flash sale has reduced it down to $9.11 per pack (only in the Maroon and Light Grey unfortunately). Still a great deal, I am yet to actual try the singlets on as it is about 2 weeks delivery estimate. Reviews seem good.
Can use the Coupon code "VIVIAN" (was randomly found on honey, looks like a referral code, min spend $49) for a further ~15% discount and also 7.5% cashback through shopback addin. Brings the total price down a lot, it's limited to 2x 2 packs per colour. I've just bought another 2 of each 2x pack in maroon and light grey. Mainly just going to be used to the gym.
Haven't posted many deals so be gentle on me!
