Where: Knows Perfume

What: To celebrate their anniversary, the geekishly fragrance-obsessed West Seattle shop is offering 15 percent off everything on the shelves.

Make that at least 15 percent. Shoppers will draw randomly select their fate upon entering; you may get an even bigger discount, you may get a free bottle of something citrus-laced or rose-spiked, you may score a sample pack or a seat at an upcoming class.

When: Friday May 13 thru Sunday May 15 during regular store hours.
