ty mothered for your fast response, i truly appreciate it, you have no idea.

You're most welcome.

i send the empty 'parcel' in a letterbox instead of walking in to post office, then when the post office weighs it and sends its off to altered address

That's precisely the approach to use.

As said, the purpose Is to show the tracking number as delivered, with no trace of the parcel (envelope) In their warehouse.

when i ask walmart for refund, it will say delivered but wouldnt they see the weight too? wouldnt that be an issue when requesting the refund

As I've stated here, the FTID method Is nowhere near perfect, has too many Inconsistencies and for the most part, Is In serious need of attention.

In answer to your question, namely the methodology you're planning to use, It's based on the grounds that the warehouse "only checks and confirms that the tracking ID has been delivered". That Is, without cross-checking the consignment on the carrier's manifest.

Companies on a very large scale, are Inundated with orders and claims on a daily basis, thus do not have the manpower to "thoroughly check" every claim. For this reason, the FTID method Is well-suited to such companies.
