What do you want a deal on? On Monday March 5th, Consumerist readers will have the chance to get up to 80% off on select products by playing in a special Jellyfish Smack Deal of the Day.

Jellyfish’s Smack Deal of the Day is a reverse auction: as time passes, price drops. The game is to buy the product at the lowest price possible. Towards the end it can get as low as 80% off. The trick is that you don’t know how many units are in stock, so if you wait too long… you lose out. Side games and real-time chat make for a rollicking time.

At checkout, players pay full price, but receive the cash back via check or Paypal within 60 days.

Vote now, based on the products you recommended, to help decide which products get smacked. We can’t guarantee that they’ll be able to get everything we vote for, but Jellyfish will try very very hard.

And sign up here so you’re ready to go on game day. — BEN POPKEN
