Zavvi is an internet retailer so it would typically be cheaper than in stores. However it does still tend to vary between internet retailers as well (comparing against The Hut, Amazon).
GAME tends to differ store to store as they match other local game retailers minus supermarkets. One I used to go to that matched the Grangier Games store opposite to it, but not HMV about 100 metres away. Similarly, a GAME store somewhere else in the city wouldn't have even matched the other GAME store.
