It may be c-c-cold outside, but at least these deals are hot....

Union Street Sidewalk Sale: While plenty of San Francisco streets seem to be having block-long sales (just walk Maiden Lane, and you’ll see what we mean), others are making it official. Head to Cow Hollow this weekend for a three-day sale that we hear from retailer Mabel Chong will feature just about everybody along this popular San Francisco shopping corridor. For her part, Chong will be offering 20 percent off new items and up to 70 percent off previous collections to make way for fall inventory.

I SpaandDress for Success: We love it when doing good leads to looking good, so you can imagine we were taken when we heard about the collaboration between the InterContinental San Francisco’s I Spa and Dress for Success. Spa visitors who donate a handbag to the non-profit organization will receive 50 percent off their next treatment booked between Monday and Friday. Call 415-616-6597 and mention the I Cessorize promotion for more information or to make an appointment.

Serial Cultura: Through Sunday, save 50 percent on this local designer Jennifer Jennings’ printed scarves when you buy online and use the discount code “scarves” at checkout.

The Firm: Today and every Friday going forward, this Washington Street boutique invites you to get ready for the night ahead during its Pre-Party at The Firm event. Roll up between 4 and 6 p.m. for wine, cheese, 30 percent off all merchandise and additional markdowns on already reduced items.

Cruz Skateshop: Looking for steals on wheels? Try this Mission destination for roller girls and skater kids of all ages. Bring in your old skates for a free inspection from the shop’s team and stay for the weekend sale, which includes longboards marked down to $100, Vox shoes starting at $30 and t-shirts going for $10 a pop.
