In addition to the AliExpress Vacation sale codes is the "Spend & Save" promotion where you'll get US$3 off in increments up to US$9 on selected items. Eligible products will have "US $3 off every US $30 spent on promo" in red text above the price and the discount is applied automatically at checkout
Edit: Some products may have a US$2 off every US$20 banner instead.
The discount can be used multiple times and stacks with Store Coupons, AliExpress Coupons and Cashback.
Nice Clear, just noticed the Pagani Design PD1644 40mm chrono for US$50.04 + GST delivered.
Dropping a comment here to see if it gets the discount. JOMW review.
