Does anyone have experience with seller Kron on cartridges?

How is his feedback?  If he is a long time member with good feedback then the risk is low.  You could always ask him if he will take payment via PayPal if you pay all the fees.  Worth a try. 

I bought a kiseki blue NS cartridge from him. It was a smooth transaction and I paid by PayPal. Maybe he has changed his payment policies.

I’ve purchased two carts from Kron with no drama, Paypal takes 4.5% for international transfers not to mention the less than ideal exchange rates. if you pay by wire its probably less than the fees Kron will tack on to cover paypal. He’s legit in my mind.

If you will pay by wire transfer you have zero protection, if it will be your first purchase from no matter what seller, my advice is to stick with paypal only (not "family and friends" or "gift", but "goods" only) with full buyers protection guaranteed.

Everyone can make a mistake, you will pay for it if you’re not protected.
It can be a postman or seller, we heard all those stories here on audiogon many times.

If someone else has bought anything from the same seller how can it help with your case ?

Stay protected by paypal buyer protection, this is how it should be for the first transaction at least.

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.
