Where can I find individual CFL bulbs?

Hi,

I have noticed that ever since there has been a good presence of $2 off coupons at retails stores like Walmart, Cdn Tire and others that we don't see individual CFL bulbs for sale? Most of the packages are with minimum of 2 CFL bulbs.

Cheapest I picked up 3 bulbs in a package after $2 CPA coupon was $7.50

I wanted to grab some bulbs with few extra $2 coupons that I managed to grab at walmart. To take full advantage of coupons, it makes sense to remit them on individual packs but unfortunately, I cant find any CFL bulbs alone.

I have a feeling that it is done on purpose by retailers so that less discount is applied per bulb?

home depot has a wide range of bulbs...but it makes more sense to go with their value pack (8 bulbs for 15 bucks)

Home Depot also sells their Philips bulbs individually..
