Considering the Z Flip 4 retails for $1059.98 in the 256GB model, this is one of the most outrageous savings we’ve ever seen. This not only includes a free Silicone Cover with Ring in a choice of colours worth $39.99, but a free $60 upgrade to the 256GB storage capacity. 

In total, you’re getting $1,099.98 worth of kit for just $99.99, or $139.99 if you want a Bespoke Edition rather than one of the regular colourways.

Of course, this isn’t just a voucher code mistake, so you will need to trade-in an old phone to get this deal, but thanks to enhanced trade-in credit, you can get a ridiculous $900 for your current phone.

You will need to have a Galaxy Z Flip 3 (256GB) or a Galaxy 22 Ultra in good condition for this top level of credit, but it’s an amazing offer if you want to upgrade from the Z Flip 3 to this new generation. 

Good condition means the phone needs to comply with the following: 

Device turns on and boots normally Charging port supports charging & data transfer All software locks are disabled, accounts are removed, and the device is factory reset Camera works and lenses are undamaged Screen and body (front and back) are free of cracks Device is not on a banned list 

Even if you don’t have those two models, other enhanced trade-in credit deals are available such as $750 for the S22+ 5G, or $700 for a 128GB Z Flip 3, S21 Ultra or S21 FE. Even if you have a cracked Galaxy A10e, for example, there’s still $300 of credit on offer. 

You will need to be quick as the enhanced trade-in credit and additional benefits end on 25 August. 

Got your eye on the Galaxy Z Fold 4? Well, you can get even more on your trade-in at a whopping $1,000 for the Z Flip 3 or S22 Ultra. There’s also a free $120 upgrade to the 256GB model and free standing cover. 

You could get $2,009.98 worth of Samsung gear for just $799.99. Again, make sure you place your order with trade-in before 25 August when the deal ends.
