I have had only a single (last!) experience with WineBid, buying from a couple of auctions and then arranging "temperature controlled" shipping.
The issue is that the wine came A WEEK EARLIER than they indicated when arranging shipping! Early is good, right? Not when you're out of the country and arranged a shipping date based on when they told me it would arrive.
I emailed them and it took DAYS to get a response while the wine sat in a hot warehouse baking. I asked for a refund and they said no because "the wine arrived when expected" except -- (i) the wine never arrived (it was undelivered and returned to sender), and (ii) it was expected a WEEK LATER.
"Molly" of customer service was neither understanding nor polite.
Some of the wine in the shipment was 50 years old so shipping conditions and timeliness matter. But apparently those things (and customers) don't matter much to Wine Bid.
