Doesn't seem to be anyone doing bundles on the switch but saw in store adverts today for the midnight launch at smyths.
310 with bomberman (saving you 15 quid on bomberman) or 1-2 switch (saving a couple quid) or another that I cant remember
320 with zelda (saving maybe 8 quid on zelda depending where you buy it from)
This was only worthwhile for me cause i actually wanted bomberman but wasn't keen on paying 45 quid on it. Its still a better deal with zelda than most places which just charge you individually for each item.
