Anyone else collect ERTL banks?

At one point I was collecting the automotive banks by ERTL.  They seemed to come out each year between Thanksgiving and Christmas.  The stores used to carry them.  They were panel type trucks, painted up with the companies logo.  I have ones from True Value, Agway, Ace, and a few other stores.  The prices seem to go up each year, to the point where I decided to stop collecting them.  When I started, they were $10-15 each, now they are over $25.  

I see alot of them going on Ebay for some steep prices.
