With the purchase of my Fold³ on launch I recieved £50 voucher that was taken off the phone, a free starter kit and half price Aramid Cover.
I appreciate this was launch day offers.
In regards to the Disney+ offer an eligible phone has to be purchased with certain dates etc.
I haven't recently checked the criteria for Samsung Boost offers.
What happens when you try and redeem.
Daily Driver > Samsung Galaxy s²² Ultra 256Gb in Phantom Black.
The advice I offer is my own and does not represent Samsung’s position.
I have no affiliation with Samsung.
@Schnuupi: I'm not sure where you are currently based, however if you purchase the Galaxy Z Fold3 in the UK between 01/07 - 30/09/2022 then you are in fact eligible to claim 12 months of Disney+ as part of the Samsung Boost promotion.
