My 10-year-old daughter collected the missing piece in the DreamWorks Heroes series the other week. Shrek, himself. Forty-two cards and out - the satisfaction was palpable.
The hologram cards were a brilliant marketing ploy by New Zealand's most expensive supermarket - you spent $20 and got a card. Shop there and keep the kids happy was the not-so-subliminal message.
Of course, Shrek and Co are now so last week as a new fad is pushing the buttons.
Brightly coloured mini rubber bands and a plastic loom to create wrist bands, ankle bands, neck bands, whatever have gripped the tweenies' imaginations.
It pays to shop around. The loom sets were under $4 in one glitzy, cheapo store or more than $20 for something very similar at Warehouse Stationery.
The holidays are almost over. What will be the buzz back at school next week ... and how much will it cost me?
