These did not fly well up here, not well at all.
Point: we never got the Imperial forces four pack. Dumb. Anything with a Vader sells, throw in a "new" astromech and two army builders - well duh.
Point: Bounty hunters sold well. Why? Boba Fett - 300th. That works. Throw in a "neat" bike and well, and. Um, ok that's it. The rest of the pack was ****. Aurra Sing clearanced at $1 up here at Walmart. I see the point of Hasbro putting her in, given they shipped all Aurra figs north of the border, but Bossk? Old Bossk, new Bossk and oh look, let's release it again on yet another cardback

Point: Hoth four pack sold well. Most of it not too exciting, but a different Tauntaun and that's cool. Throw in a "new" astromech and you're doing ok. Should have had a snowtrooper in there.
Point: Carkoon was marginal, but at least the figures weren't still widely available. The Han was quasi unique, the skiff guards for Canadians may have been new, the Cinema Scene 3 packs weren't widely distributed up here. The gun was a boring major accessory, most people picked up the deluxe Leia not so long ago (though it was never available in Canada at regular retail either

). End result was moderate to good sales, but I can still find these today.
Point: Jedi 4 pack was awful, just awful. $40 for this (oh, I didn't mention the Canadian retail price? yes, that is the price fourty ******* dollars). Most if not all of the figures were still on TRU's pegs (at full price) when this set arrived. If they sold one locally, I'd be surprised.
Add the last two four packs relative success and you end up with....
Point: Kaadu 4-pack never showed up here at retail. Not that I would have bought it, I have a serious Ep I mental block going on and don't own any Ep I beasts anyway, but I bet it would have sold well.
Anyhoo, I'd be surprised to see TRU jump on board again up here. They never clearance and the shelves are plugged with crap. They're a neat idea, when well executed but I've only bought have of them and should have skipped a couple of those anyway.
