What sorts of items are available there in the Philippines? Good question. Here are a few more websites that you might find interesting.
Makro - This is the supermarket for businesses. They sell in bulk and are meant for Sari-Sari type stores ( the stores that sell out of your home - survival profit only) and maybe restaurants. Check out all the strange things that are for sale there in the foods department.
The Makro site runs a lot better than some of the others here. It's quick and easy to navagate through their website.
They are still showing a Christmas theme on the site but check it out.
How about appliances? Take a look through this one.
Abenson - It's all imported goods. There are lots of choices and departments on this site. To compare, remember that the prices you see should be divided by 40 and then multiply by 1.1 for the VAT tax. That's the out the door price without the delivery charge which might be another 200 pesos, depending on the items bought.
Most imported goods here are much more expensive than the US. Take a look and you'll see.
