I just got back from CVS who is having Buy One Get One Free Zhu Zhu items. You can also get a coupon for BYGOF here. Combining both specials, you bring 4 pets to check out and only pay for one. At my store they were $9.88 each, so I got 4 for $9.88 + tax. The fact they also have the accesories on sale, is a pretty good deal too!
