I see you've decided to buy hardware wallet, and it is definitely a good investment. Ledger always has some discounts, but as far as I can see there is no offer at the moment. I also do not see that there is an official reseller in the Philippines, so you will have to order directly from Ledger France. I am not sure how things in the postal system work from the EU to the east, but I know that from the opposite direction the situation is rather chaotic. One package I ordered a month ago from China has been in the Netherlands for over 2 weeks and hasn't moved yet.
