i also learn from the thread

1. in google chrome, right click on the lazada page then click inspect
2. go to console tab, paste this script

3. press enter and wait. if u key in correct u will see this "wait" keep on going in number. meaning it refreshing i guess. wait there until u see voucher code appear.

of course the more u open the higher chance u get. once u get it then u quit all ur chrome and reopen back chrome at incognito and repeat the steps above.

continuous 33 codes, without 29%, i really gave up now
