Woot more expensive than Amazon?

I’m not a big shopper at Woot, but do check out their email ads occasionally. I looked at a pair of gloves for $16.99 at Woot
but didn’t see any reviews for them there, so checked out Amazon and found apparently the same gloves there for $12.99, with plenty of reviews. [Even had the same misspelling of Simplity instead of Simplicity there!]

Does this price differential favoring buying from Amazon happen often?
