B&H has launched its holiday season deals page. The page includes several deals that are valid for 24 hours, as well as longer-term discounts on nearly 10,000 products. The full selection can be overwhelming, but the page includes a thorough system to narrow the choices by brand, product type, and price. That said, if you are particularly focused on deals from one of the major camera brands, you can find brand-specific sections of the holiday deals here: Canon, Nikon, Sony, Fuji, Panasonic, Olympus, and Apple.
