Restoration Hardware has a huge warehouse about 20 miles north of Baltimore that is open to the public once every few months. Unfortunately, they're closing this warehouse and moving it, and it will no longer be open to the public once they move.
Their final sale is from July 8th to 12th and they're advertising savings of from 75% to 95%. I have gotten some incredible deals there, including crystal ornaments, originally priced at $12.99 for 49¢. I bought some pewter vases for $2.00 that were originally about $25 each. Here's a post about some of my great deals. Most of their furniture is too big for my house, but their smaller things were great deals!
Here are the details of the sale, with times and directions.
