Don't expect it to arrive at all. You should've just bought a card online that doesn't go thru customs (from the online shops where you buy gifts for the Philippines).

We sent 2 small packages of coffee for my parents in the past thru Royal Mail. One arrived after 3 months and the other went missing. We sent it via air cargo and supposed to arrive in 3 to 5 days. After probably 14 months, the other box turned up and my mum had to pick it up from the post office. It arrived from UK to Philippines after 3 days from the day we sent it. It was stuck in the Philippine customs all those times. Do not trust Philippine customs in anything, whether letters or packages.
