HUKUBUKURO is changing

I  went to shopping center yesterday and watched many kinds of "HUKUBUKURO".That is Japanese traditional style of sale,several goods and wears for sale are in one cloudy package. Japanese "HUKU" means luck. "HUKURO"means bag.So "HUKUBUKURO"means a lucky bag. I think this luck is for consumer and retailer both if possible.But nowadays the economy is not good, so customers are not so active to buy those HUKUBUKURO easily. It needs something new device to sell those goods.I think that some Free strategy is effective for that.
