Not so much that they're insignificant, but that they don't support your point, and for three reasons. One, because they're OPTIONAL bundles. You aren't required to buy them, so unless it's an INCREDIBLE bundle (see: free game), there won't be THAT many jumping on it.
Two, because they're OPTIONAL. People that DO buy those bundles are doing it because they want the game. Any store that does a bundle like this isn't doing it to move the game units. They're doing it to move the SYSTEM units, and it's usually not the only bundle they're doing anyways. They know that luring people in with a game like MKWii will motivate them to buy their system instead of the competitor's, and even so, it's almost never the only bundle they're offering, so people still have to make a decision on which game to get. The fact that they're walking out with MKWii still supports it being a good game.
And three, because, ultimately, the UK only accounts for about 20% of Others region sales, give or take depending on the week. That means approximately 1.9m of the game's nearly 22 million sales. Since it's an optional bundle that hasn't been around the entire time, we'll say it counts for a very generous ~25% of those stores' sales (particularly since there were so many Wii owners before the game came out that obviously DIDN'T buy via bundle). You say those stores are the "biggest street game stores", so I'll give those two stores the benefit of the doubt with a really good marketshare and say they take about 90% of the nation's total videogame sales. That'd mean they sold about 1.72 of the total MKWii sales in the UK, so the bundle's 25% then would count for 432,450 units.
Which is insignificant in the end, in comparison to the overall game sales.
