Does anyone have experience with seller Kron on cartridges?

You could offer to pay some or all of the Paypal fees if you'd prefer to pay that way.  You can't have your cake and eat it too.  The guy has a 100% rating and over 1,500 sales.  

Paypal protect buyer with full refund even if the item lost in transit between seller and buyer. 

Thanks everyone, he looked fine in terms of feedback and he does offer PayPal but adds the 4.5% and another $40 for shipping and says he doesn't add either for wire transfer. For a Hana ML that's $85. I'll probably do PayPal anyway but thought I'd ask for direct experience with him, particularly if someone used wire transfer. Like they say "stuff happens" so you never know, better safe than sorry. 

definitely, especially for the first purchase

I received my Benz cartridge from Vincent today.  You get incredible transit time for that $40!  We finalized the deal Thursday evening around 9pm cst, which was 10am his time.  He shipped it and I received it at 11am Monday!  It was in the original box as pictured in his ad.  That box was completely enveloped with bubbles tightly packed in a box then inside a shipping envelope.  It was delivered by FedEx.  

There are likely cheaper transit options but making it priority helps ensure a safe delivery.  I work for a large company that has a global account with FedEx.  Our prices often are less for overnight compared to ground.  This is done to incentivise an overnight shipment.  If the package has an opportunity to lay around in a warehouse it presents the possibility for issues to arise.

It was likely the smoothest transaction I have had.  He offers very nice prices on new cartridges.  Nothing to worry about with him which as others noted you can easily tell from his impeccable feedback.
