There were country-specific coupon codes published on Couponsfromchina social channels and price alerts. Coupon price may vary by country, because there’re different VAT rates, shipping cost etc. There is a chance that some latest coupons are still working:
Old coupons (from the oldest to the newest): BG20236Tool, BGBFDAY8, BGNEWYEAR8, BGESJY8
(these coupons are old, so probably won’t work)
