Is Gamut Packaging a legitimate supplier?

Not sure if this is allowed but I’m unsure of where else to ask.

I recently made a purchase for some plastic pop top bottles and I was emailed asking for ID verification. I know I should have just cancelled right there but I really need the bottles and the price was reasonable. I just figured since it’s packaging made for cannabis, that is why ID verification is used. So I submitted the photos and because my ID has my previous address, they are now asking for pdf files of a bill or bank statement that shows my previous address.

This has me concerned that the website may not be legitimate. It was only a $30 order for plastic bottles and I don’t understand why it requires all these extra steps just to prove my identity.

Has anyone here ever ordered from them? I just needed the bottles for raising my spider slings and I was looking for a website that could beat Amazon prices.
