Push style body rivets for mud guards

I have broken mud guards on the front of my 06 and bought some Weather Techs to replace them. They make use of the stock push body rivets that the originals use, unfortunately I broke 5 of the 6 on the front mudguards.

Anyone know of a source for these that is cheaper than the dealer, last plastic clip I bought from them cost about $3 for a tiny plastic dash clip and I was hoping to get 12 or so of these things so I could do all of my mud guards with new ones.

And if you need new screws as well use these.

They may be available at the local auto parts store.
