For the record:
I place an order with MFS after they sent me an email announcing the changes to age verification for the FDA regs. I ordered two Kanger kits and went through all of the age verification by giving some information from my drivers license.
My various addresses:
DL = 4 year old address I moved from
Billing = PO Box
Shipping = Same PO Box, but listed as xxxx Street St #xxxx because many residents don't have mailboxes in my town and we list the post office as a street address and Fedex/UPS have agreed to deliver there.
I thought it was going to be a nightmare and that I'd never be able to order online again. Went off without a hitch, not even a hickup. Have a
tank on one of the mods right now.
A lot of these vendors are going to do things to comply with the law, some may make better systems than others and they'll all figure it out eventually. In the meantime I'll only go through age verification with vendors I trust and hope the systems they use don't have mistakes.
