I've ordered many times (way too many) from oozak and have had zero problems. I always got my order within 2 days. I would not count them out because of this one incident. I haven't even known them to show markers in stock if they weren't in stock-they seem like they have a running inventory and it automatically marks them OOS if someone buys them all.
Carpe Diem, on the other hand, has done all of the above. It almost made me wonder if the PP meant carpe diem rather than oozak.
