By the time we came across this series, the books are already way too simple for Chip to read even on his own.
But the stories make him laugh so hard and for that alone, E thinks it is worthwhile to pay 5 quid for each. We bought almost the entire series from The Book Depository which ships them for free.
While E didn't feel the pinch, I certainly do. But I am consoling myself that we will have a new user for these books very soon.
One thing for sure - I will be reading them very frequently to Baby O in a few months' time. At the very least, I know it will make me feel better about the purchase.
