Mega Bloks - Teenage Mutant Ninja Turtles classic series:  $5.34 each @ Walmart.ca (RSP:  $9.97 each)

They were on clearance for $7 each, and then I had a $5 off coupon.   I definitely didn't want to pay full price for them, and they didn't seem worth that much since they're so tiny.  This is about the most I'd be willing to pay.
