Dyson's vacuum cleaners aren't known for their affordable prices, but they do have a reputation for cleaning stuff real good. The handstick units are particularly popular — and expensive — but right now you can grab the V6 Animal for $320, down from the RRP of $549.
That'll put the price to $319.20, with postage completely free.
Keep in mind you have until May 8 (or until it sells out) to grab the vacuum at this price. There's also a bunch of other Dyson gadgets on sale, if you're after something a bit different.
