I ordered from them a couple of times, because they seem to offer the cheapest price on many items. My problem is not the transit time per se, but the time they seem to take to ship the item--several days, it seemed, almost a week in one case. So no more zoverstocks. And don't forget, the "shipment date" is the date they tell Amazon they shipped it, and putting it in the mailbox on Saturday afternoon counts as shipping it, even if the mailman doesn't pick it up until Monday afternoon--and they may have told Amazon they shipped it on Friday afternoon....
Others who seem to either be slow to ship or to use inflatable dinghies are MovieMars and marvelio, which can take up to a week longer than other Marketplace vendors to get to me.
