Winemarket has 20% off all wines for 24 hours only. If you were hoping to stock up, from a savings perspective this is a great deal as the best we've seen in the past is $50 off (min. spend $120, one time use). Spend more than $250 and you're saving more. Even for lower priced items, you'll still beat the $20 vouchers that crop up from time to time if you spend over $100, and the $30 vouchers (much rarer) if you spend over $150.
Normal caveat with Winemarket, choose your wine carefully!
