I don't know what is happening lately but I usually have Really good luck with ebay. All three of these happened this week.
First: I bought a pony poster and when it arrived was put into a rectangle over sized box which was smashed up some. So it caused damage to the poster and the sender had folded it! Completly ruined
Contacted seller and they have me the purchase price back at least.
Second: I purchased a G4 pony from douhikeshop and they sent the wrong one. I PM'd them and told them the difference to a collector is an issue. They said they are sending me the correct one and I can keep the wrong one too. So hopefully it will get corrected.
Third: purchased a couple figurines and Christmas ornaments and one figurine wasn't even in the package! I've contacted the seller but haven't heard back yet.
I know a couple issues have been resolved but it's still a pain and waste of time contacting and sending pictures. So hopefully bad luck ebay will end soon.
*End of Rant*
Edit to add: Third seller found the missing pony and it is being sent.
