Impulse purchase

Yesterday I stopped by a drugstore, and in addition to what I went in there for I made an impulse purchase at the register. I normally don't do that, but in front of each check out counter was a display of Buyer's Choice compact fluorescent light bulbs for a price of $2.00. The handwritten sign below the stacks of packaged, spriral bulbs promoted it as an advertised special, no coupon required.

Aside from the excessive plastic packaging and the caution on the back that says lamp contains mercury (it does, however, give a web address for lamp recycling - www.lamprecycle.org) this is an impulse purchase one needs not feel guilty for indulging in.
