Do the math on petrol/transportation/time/frustration spent looking for figures like this and you'll realise what I did a long time ago. I haven't bought a TF from a bricks and mortar store in a veeeery long time. If I need a figure in my collection I've learnt not to trust the inept stock practices of Kmart/Target/etc for anything beyond wave 1.
Having said that, some fans love the thrill of the chase...
