Aldi has a really nice LED desk lamp I've been using. $20. I actually got mine on clearance for $14. Keep an eye out for it. They are seasonal.

Does everything the $80 ones do. date/time/temp a USB output. Can be powered of a USB port also.

Link?

I don't think you can buy anything at Aldi online. It's in-store purchase only.

What store?

Aldi they have a store locator..none in AZ
