If gusto mong maka tipid, with less shipping fee but with less security din ng bibilhin mo then dun ka sa mga retailers nila, dun ka sa singapore based para mas malapit at try to see if may voucher or sale sila. OR somewhat may nakita akong seller sa lazada which madami ding 5s review though like ng sabi ko less secured ito kase it can be tempered, or much worse may backdoor planted galing sa mga masyadong techy na retailers.

And recommended pa rin is dun direct sa shop nila, cannot remember about sa fees, basta alam ko walang charge dun sa mga binili ko. Sa payments nman, they can accept paypal, mastercard/visa whether its credit or debit card, and ofc BTC.
If may gcash or paypal ka you can use their virtual card.
