I noticed now that AliExpress accept PayPal as a payment option, you can get an instant US$2 discount on orders over US$20 when you select PayPal as the payment method during checkout. Anything below $20 will give you a Select Coupon after payment.
Discount might be 1 per account.
AU$ based on current Mastercard rate at time of posting.
I have no problem with 28 Degrees yet, but some cards get charged with cash advance fees if paying by Paypal
