[EDIT - it is 100% fake and not regallabs]
OK, the site is not hosted conventionally, it's behind an AI driven wall, it'll take a day or two to find out who's behind it and not going to post anything until I've spoken with him directly out of courtesy and respect.
The prices look correct, the postage too, it's his list but with 3 extras I don't believe he has and had no intention of providing in the near future.
Perhaps it is legit and he's clearing stock...
I can't do it for reasons I can't post, but if someone makes an order and receives payment details, if you DM me any 1 letter from the first name and any 3 from the second name (fill the rest with *) I will confirm if it's correct. Don't post on here, DM me. Obviously don't make the payment until you know it's legit. Anyone can do a dummy order and not buy anything. Someone with a reasonable post count and reputation please.
I notice both the email and website use regalabs, not regallabs (double L). Someone on here will confirm, but my understanding is that the first has been used by scammers in the past, he uses the second, I may be wrong.
