Have a look at this:

I dont think it was on sale or anything (I bought it when it was like $25), I just needed a magnifying light for the shed and this seemed like worth the punt. It arrived and was pretty good quality.
Went to buy another as I liked it so much and could do with one permanetly mounted in another spot (I have a good size shed) and the price was 10x!.
I looked today out of curiosity and its dropped by half!
Anyone know why they would change this much? Or was I just lucky?
A lot of the sudden fluctuations are due to price matching someone else's sale price. As soon as that smaller company runs out the prices can bounce back.
