Being using them for 20 years in four different countries: all excellent generally.  Quite happy to pay the 'ORG616 Premium' for the convenience.   I have made recommendations as regards service improvements in past (such as being able to sort by price & shipping combine to stop £0.01 goods with £2.50 shipping; put parcel in 'Special Place behind the rubbish bin') and then noticed them change policy; I'm sure others suggested the same. When things go wrong - and they do over that time period due to sheer volume - they have done what was needed as quick as I expected. A minor point, hence 4 / 5 stars, is that recently they have let some products with misleading descriptions be sold by the 3rd party sellers - and seem to be utterly incapable or unwilling to remove them and keep them removed despite multiple reports.  True, the external vendors are being deliberately misleading / deceitful....but ORG616 runs the site, they take the commission - so it is their responsibility to clean up their 'house'; the ASA agreed.
