i would use escrow every time normally
sedo will take ages getting back to you if emailing and theyre shut weekends which makes them a nightmare imho, they dont deserve the business
the big downside is $ to £ as people say
i haver been buggered a few times by barclays
lets use an example
if you get say $3000 for a domain and xe.com says it's say £2000 (for arguments sake) or any other online currency coverter
expect your bank to give you like £1500, not kidding
they work off a different exchange rate
banks truly are lowest form of life
shame paypal cant be trusted for people you just got approached by and have struck a deal with
chargeback too risky, nontangible goods etc
if it's a proper uk business buying, just get them to send a bankwire to you, then transfer domain
there are guarantees they have sending direct to a bank account, they can get a reversal if they feel unsafe or feel a scam has occurred, plus you have to jump through a lot of hoops to get a uk bank
if someone screwed you over and charged back a bank transfer for no reason just report to police as fraud, thats way i look at it
i feel very safe sending money to uk bank accounts and receiving
in fact whenever i sell via a non online platform, ie godaddy, forums etc, by email correspondance, i just bill them an invoice with my bank details
when it lands in my bank account they get domain
i have never had a problem. and most of my buyers are not brits. tend to be europeans, italy, france, germany, sometimes america
obviously europeans hit you with euro offers, i just tell them offers have to be in £, and when they send to my bank make sure they're clear to teller that it is in £ to arrive other ends
with yanks i tend to stick to $, as theyre a bit dense

i use escrow.com with them. they are happiest with that
