i've seen the store many times but have never gone inside as i haven't really been looking for a bag. i did see the store in their old location though, which was quite small. i sometimes drop by their watch store (same company) and a few bags would be on display, like i've always seen a chanel gst tote and it retailed for about 160,000 pesos = 3,700 USD if i remember correctly. not quite sure if the bag was brand new though.
are you planning to visit? here in manila, a lot of resellers are also online, on facebook and multiply, with both brand new and pre-owned bags. i would think they'd allow to do meet-ups so you can view the bags. there's also another store similar to bagaholic in greenhills, san juan.
hope this info helps!
