I also pre-ordered an S24 Ultra online. Here are the freebies and discounts I got:
less ₱1,000 for ordering for the first time on Samsung.com
less ₱2,500 using the promo code GALAXYAIS24
less ₱10,100 for trading in a Note 20 Ultra 5G
less ₱16,000 additional add-on by Samsung for the trade-in
Free upgrade to 512GB for pre-ordering online (basically an ₱8,000 discount as this is the price diff vs the 256GB version)
Free Samsung Care+ for 6 months (worth ₱3,599)
Free Galaxy S24 Ultra Silicone case (for choosing an online exclusive color, case is worth ₱1,190)
Free Galaxy Watch 6 (40 mm) for using the promo code GALAXYS24LIVE (watch is worth ₱16,990)
Free shipping
Total price will be ₱55,390. It won't be credited yet until the trade-in is done.
I also plan to sell the watch for ₱12k and the free silicone case for ₱800. Net price is not too bad for a TOTL 2024 Android phone with 7 years of OS updates.
Btw, Metrobank and BDO cards also have the option to do 6, 12, 18, and 24 mos 0% installment plans.
