There's a bittersweet feeling that falls around this time each year — the summer is finally over. And for much of our lives, that meant heading back to school. But if your memory serves, the return of classes also came with a silver lining — the annual back-to-school shopping trip. Except now that you're grown, sticky notes and highlighters don't really seem all that exciting. After all, you can't go to Staples and get that IWC watch you've been drooling over all summer. You can get it on eBay, however — and depending on the model, you could get it at a huge discount. Maybe it's a Portugeiser at 32 percent off, or maybe a Portofino at 15 percent off. Right now, eBay is offering a broad selection of IWC watches for up to 30 percent off. No, that's not a typo — just click the link below to start adding items to your watch list. Buy Now
