I booked with Kozmo last week, very nice and thorough, easy to understand instructions, tells you exactly what details he needs and what's important.
Will be getting my Refund today (2 days later than promised, but who cares as long as it's Kozmos usual flawless work
), will update this post as soon as the refund is in.
Check in is tomorrow, so you can expect another update to this post detailing my check in experience
Already looking forward to my trip
update: got a refund confirmation at 6:45am on check in day, quite some time later than I had wished for and the guy assigned to me didn't respond to my messages (Kozmo himself was kind enough to always provide timely responses), but so far it seems like in total (including Kozmos fee) I got a 45% discount. next update after check in
