Looks like you can hold off on that tea party for another week, luxury shoppers.

This Saturday, Sunday and Monday, The 900 Shops on Michigan Avenue is offering you a break from Chicago's typically crippling 10.25-percent sales tax by discounting all items -- including those on sale -- by the same amount. Participating retailers include Michael Kors, J. Crew, MaxMara, Montblanc, DNA 2010, Club Monaco, Adidas, L'Occitane, Charles David, Original Penguin, Solstice Sunglass Boutique, Oiliy, Bernardaud, Mark Shale, United Colors of Benetton, Galt Toys, Mario Tricoci, Christofle, Sermoneta Gloves and more. The daily parking rate will also be reduced to $10, so it'll be easy to haul away all those bags.

There's just one catch: you have to present an access pass to get your discount, available online or at the concierge desks on levels 1 and 6.
