Looks like there's many scam on this site, so beware shibas!
But there's light in the tunnel - if the package were not send in 14 days, whole sum is returned.
Worth the risk, on smaller sums, just to promote DOGE, there will come a day when this activity gets safer to do.
Good Luck to you, hope seller does not let the coin down, site backing it up is a very good sign.
