Selling limits for most sellers either jumped to crazy limits or were removed altogether a few weeks/months ago. No reason to call eBay, it just means you don't have to worry about that anymore (if you ever were, I know our limits were already sky high, but now they're gone). Concierge service is mostly useless now anyways, they removed some of the benefits from what I hear (we didn't have it), so I wouldn't worry too much. Just focus on selling.
