ask your relative/friend for a
one-day trip to
Greenhills, the biggest collection of hobby/novelty stuff in the country. make sure you've got enough Peso with you, some of the loot you'll find there are rarely seen in the U.S., and i'm not talking only of Transformers but other collectibles also.
here are some shops i know in GH and what mall are they in:
GREATTOYS
3/F Blue Lane, Shopesville, Greenhills, San Juan
Mon-Sun: 10am - 8pm
http://www.greattoys.net/ecom/BABES CHILDREN'S WORLD
2/F Virra Mall, Greenhills, San Juan
BEST TOYS
3/F Virra Mall, Greenhills, San Juan
PATRICK'S TOYS
3/F Blue Lane, Shoppesville, Greenhills, San Juan
WASABITOYS
3/F Blue Lane, Shopesville, Greenhills, San Juan
http://www.wasabitoys.com/map.aspthere are many others but these are what i know of.
tip: don't forget to haggle! though the discounts they give sometimes might be minimal, but at least every Peso you save could count towards more TFs and stuff. also, ask if you can haggle substantially when buying many items at one store.
i dunno however if you can get many toys with your dollar, since Philippine stores usually sell TFs at a higher price mark (e.g. $10 deluxes SRP here @ P 700, a markup to $17). just bring a lot of dollars with you if you wanna maximize your toyhunting experience here.
