SUMMER
Sharesies posted another promo code for new users. $10 signup bonus will be added to your portfolio when signing up using promo code ‘SUMMER’.
This gives less amount than last promo (https://www.cheapies.nz/node/31226) which just ended, but it is still better than usual $5 referral bonus.
(Since it’s a promo code not referral, i assume this would work together with a referral link like previous promo. But not verified.)
Go for it and add promo above should work!
