Has anyone ... from within this forum (not the website you claim is yours) purchased from them and can you vouch for them?

To the OP do you know how escrow works?  Choose an escrow service to whom you give the tracking of the pack when you ship it and it lands (is delivered, confirmed) the escrow service releases your funds to you. 

There are escrow provider's who don't need or care about what the buyer cares to say or try to do/say to scam a free product our of, there are many who only require proof that you've delivered and if the buyer has dispute that they must provide picture's with succinct explanation for how they were 'scammed' by you and why they should have their funds returned to them with stringent guidelines by the escrow provider.

You say you're not amateur but:
a. You don't use an escrow service ... on your website, or on here ... period ... that's retarded ... what 'professional' vendor does not use escrow?  Come on now.

b. Don't even seem to understand how escrow works, the buyer can't hold you hostage through escrow just by saying they were unsatisfied, if they receive what you advertise the escrow service releases your funds to you.  DNMs have been doing this for so many year's with so many market's with so many scamming fuckhead scum that escrow services have learned all the little tricks these bitches try to pull and they offer the seller the exact equal protection that they offer the buyer.  YOU SHOULD KNOW THIS IF YOU ARE NOT AN AMATEUR

c.  How the hell are any of us supposed to know that that site if even yours?  I could start a thread here and say I am long time established seller, I are long time on the site http://www.verifiedacc.com/ just believe me because it's my site.  What you question it's my site or not?  I am not amateur it's my site ... do you see the LOGIC FAIL here?

d. Where is your grams account?

e. Where is your PGP so we can even make an EFFORT to recognize that you are the real owner of that site and not just some dude who created an account on bitcointalk.org and said that site is his so we must trust he is legit and not not an amateur.

If you're pro you at least link us your grams, your PGP, a market, source, credible outside vendor SOMETHING.

But I relent ... has anyone (in good standing with a high reputation account here) on this forum tried this guy's service and had success and can vouch? 
If not, you're going to have to at least give out a few free vouches to high ranking member's (i'm not trying to mooch a vouch, i'm not a high ranking member and thus not suited to be a credible vouch for your service).

Why am I still going on?  Cuz I actually have real interest in such a product/service, but I need proof of some sort (that's not you linking a site that sell's the shit and just saying it's your site, that proves nothing.  I own google.com biches, mmk).

Do you even have a PGP keypair so your buyer's can send you their sensitive info (shipping address) NOT IN PLAINTEXT ?  You MUST have a pub key if you're not a RANK AMATEUR so PLEASE tell me you have .. even KNOW what that is lol.

Where is this website of yours hosted and to whom does it belong btw?
