Now I know this may not be a deal by normal standards however I know there are places which will charge you $1-2 to recycle each of your compact fluorescent bulbs however Ikea is doing it for free!
Because of the mercury in fluorescent bulbs you should not put them in your normal rubbish bin as the mercury can pollute the landfill and groundwater.
IKEA offers customers a used light bulb, compact fluorescent and household battery take back service. These products contain small amounts of chemicals and should not be placed in landfill. So please bring your used bulbs and batteries back to IKEA and deposit them in the take-back containers, located just after the checkouts.
Not a deal because Ikea has been doing this for ages, and also there are other places to recycle fluorescents and batteries for free. Belongs to forums.
