I have way more stuffies than any little could ever need. Most of them are from thrift stores, flea markets or EBay because I like to get the stuff I had when I was little. I know I've paid quite a bit for some in the past. Sometimes when you have a friend calling out to you you just have to adopt them.
As long as your bills are paid and your not being irresponsible with the purchase, then by all means, go for it!
