Once you register and login, there are various red envelopes scattered on the pages. Clicking on these, activate various offers such as
$10 off $60 spend
$15 off $70 spend
$20 off $80 spend
10% discount
30% discount
mystery discount (I got offered 33%)
buy 2, get third item free
Remember to save these codes into a separate document and use the best offer that gives you the largest discount. The codes are unique to each login.
With the discounts, I noticed that many items are already on sale so a 33% will only give you an additional 3%, so it only applies fully to non discounted stock.
May work with Cash Rewards and ShopBack but not 100% certain.
