My ReStore has clothes, books (formerly, but "too many thieves" they claim), tools, electronics, CDs (formerly also), light bulbs, appliances, renovation materials, etc.
In regards to pricing, the store is definitely hit or miss. It all depends on the person stamping the price stickers and their current mood. I've seen cases of fluorescent lamps (6pk) at $6, or $1/each lamp, but I've also seen cases split up and lamps (attempted to be sold at) $5 each. THEY'RE F32T8s FOR CRYING OUT LOUD. Additionally, my store has ZERO issue with mercury or any of the Hg stuff. Anything that comes in is sold. Just got some metal halide lamps from there last weekend.
Though most fixtures they sell are resi-grade stuff, I've caught older shoplights and whatnot before, and usually for not too much.
Don't even get me started on the prices of LEDs.............. you can get a pack of four incandescent lamps for $1 or a pack of three LEDs for $8. And they're not even name-brand; only Up and Up garbage.
Though I guess luckily for me the employees tend to give me discounts on unpriced or even overpriced items. There's definitely an occasional 25 or 50c buying spree to be had......
Though honestly in regards to lighting, one of my other local ReStore has A TON of it! Fixtures everywhere. Industrial shoplights (NOS and used, mainly Simkar), Cree LED HID retrofits, instant fit T8s, bulk packs of GE LED PARs for like $2 each, etc. It's just that it's never stuff that I want or need.....
