My most expensive toy is the 02 Revolution, but I didn't pay $92.99 (or even more on some other sites) for it. It was a buyout review, plus I used my points toward it, so it actually ended up costing me very little.
The most I've paid for a toy was the $71.64 that I just dropped on the O2 Rascal. It's discontinued and Eden no longer has it, so I had to crawl Google until I found a site that still carries it. I'm going to sweat bullets until it gets here, since I'm not sure if the site's reputable, but it was better than one site that triggered security alerts in Firefox when I went to the checkout page.
