From what I've read that method works perfectly except buying directly from Apple or Amazon.
Any other stores you should avoid with this method?
Also what do you use to replace the weight of the iphone? Is it fine to use rocks or something?

Correct.

Not at the time of this post.

Also what do you use to replace the weight of the iphone?

Preferably a like-for-like product, such as a dummy phone of the same make and model.
