I'm unsure how many digital delivery auctions it takes for those wing badges, but can be done. It takes more than shipped auctions because listia wants to avoid fraud of fake / junk digital auctions that fake / friend accounts may bid on just for wings to then list a major item never intended to ship (fake auction) just for the Advance = smash n grab Listia style = list major item, get credits, spend credits (mainly gin use) and begin getting items before dispute takes the credits back (by then too late)
Keep listing auctions that end successfully - I got mine at 10 but I see some get theirs sooner in as low as 5 (depends on type of auction, credit amount or in other words no junk auctions with low credits and shipped auctions are faster to seller wings than digital delivery) Basically you Prove yourself- you loose trusted seller if your feedback rating falls to low and the credit advance stops. Once trusted you get advance on credits right after auction end.
If you have current bids on current auctions and you go negative credit amount, then your bids are removed. The last bid if any becomes new high bid on such auctions.
not just wings, the "s" wings I ment, at that point you also get an advance on the credits from won auctions but can be taken back by dispute and leave a negative credit balance ( if you spend to soon and there is a dispute the credit amount gets removed from current credits even to a negative credit amount until dispute resolved, so be cautious)
Must have trusted seller wings first before gin is an option, once you get wings you will see the enter gin amount box under the start bid amount box. Starts at 2000 min and cost 50 credits to use, if used you get the 50 credits back and pay a credit fee of about 200 - the higher the gin the higher the fee, it will tell you the fees in a prompt to confirm or cancel - the 50 comes out of your current credits (must have the 50 or no gin use) and the "use fee" gets taken out of the gin amount at the same time 50 is refunded.
