What do you do when they ask for a video with the ticket number written on a peace of paper ?

I'm providing them.

That was my fear too..also do u mean buy online from a big retailer store or instore?

It's doesn't matter as long you have a receipt that you can edit everytime you need.

How do you provide them if you aint got the product? We’re talking about the s/n method right?

Yes the SN method.
1.You can order from shop then legit return( use the item for pic/video till you got your replacement)
2. You use Logi services that offer this stuff.
3. You are good at editing stuff and make your own materials
