Well, I ordered myself the new S25 Ultra and also the Watch 7 by taking advantage of Samsung's 30% discount with an additional device upon ordering a S25. So far so good, however, I also had a £50 Samsung voucher to use when ordering any S25 (obtained by registering interest in the pre order event).
I also read in the pre order launch email, that I could use a 10% promo code (APPS25) if ordering through the Samsung Shop app. There is also a code to receive free Ear Buds 3 with any S25 order too.
Armed with these promo codes, I went to place my order, but soon found out that if adding additional devices in your basket (to achieve 30% off the added device), you cannot use the free Ear Buds code too as it will cancel out the 30% Discount.
Nor can I use my £50 voucher if I also use the "APPS25" 10% off the basket total.
It's either or.
So, I took off my £50 voucher to get the better financial reward of 10% off the total.
So the £50 voucher and the free air buds could not be added unfortunately, but I saved a heap anyway.
The reason I mention this, is that nowhere in the small print of the promotions, does it say you can't use all the related S25 pro offers at once in a single transaction. I had this confirmed by Samsung live chat too.
Anyway, can't be too greedy now, and I look forward to my new purchases!
