Hollister and Abercrombie both have really big Jean sales twice a year that I've shopped really closely. They have sales from time to time but not like the one you're talking about where it feels like they're giving them away. In my experience the first big sale is usually when it's still way too hot to be thinking about jeans & the second runs right around Black Friday into the Christmas season. I found that going into the store and texting to that special code they have at the register will usually link me to get all the sale info fastest, and this has included free perfume roll-ons with purchase & incredible fragrance discounts too. When you make a purchase also give them your email &/or you can make an online purchase that will link you to that side of things too.
