I was quoted 6-8 weeks too by Philbox. We are now 12 weeks on and still no delivery.
I don't mind them taking 12 or however many weeks to Mindanao but, I don't like when people lie to me. A golden rule if you want repeat business: DON'T lie to your customers. If you're not sure, say so.
They have lost my business as I just took delivery of boxes from another company.
