In looking it up today, it looks like Target, Party City, Walmart, and eBay all have Sonic costumes. Out of season though, you might try a year-round costume shop like buycostumes.com or something like that.
The Stores that have Sonic the Hedgehog Action Figures are:
Toys "R" Us
KB Toys (Which is now closed due to it being bankrupt)
Wal-Mart
Target
Hamleys (Only Avaliable in UK and some areas in Asia)
K-Mart
Sears (But only with the shirts that have the bendys)
and for online
ebay
amazon
toys r us
walmart
Google shopping
etc.
