Where to buy rv amiibos online

I'm having a tough time finding rv amiibo cards on ebay. Can you please comment links to this thread. I prefer to buy them in "lots" but I cant seem to find any. Even normal amiibo card lots with some rv ones mixed in would be okay too.

if you cant find any... what are the odds of pulling a good amiibo card in a pack?
I might get a 3 pack lot when I get my money. would that be a better deal?

I know you can't buy them in lots, but how about ordering from toy r us? I was considering them ^^
