Amazon has started a big Year-End Clearance sale, and part of it is a 25% discount on the current prices of 1200+ digital camera accessories. The list is very diverse, from $1000+ Profoto, to Metz flashes to $5 trinkets. We obviously can't go through the whole list and price-check 1200+ items, so that part is DIY for any items you might be interested in :)
Simply add the qualifying item(s) to your shopping cart, proceed to the Amazon Checkout page, enter promo code Q4SAVE25 and the top right corner of the Amazon Checkout page will have the 25% discount deducted from your total. This promotion expires Dec-31-2010.
The 25% discount is good for as many different products as you like. However you can only buy one of each product per shopping cart. The shopping cart intervenes and reduces your quantity to one per product. I do not know if you can buy it multiple times. I have not tried that.
Among the items spotted are Profoto, Metz, Gitzo, softboxes, tripod gear, Targus, Manfrotto, Avenger, Creative Light, Benro, Elinchrom, Interfit, Jenis, Lastolite, Lomography, Vanguard, and more, in a total of 16 pages. Products are intermixed in the first three pages, but starting with page #4, they are sorted alphabetically by manufacturer name.
There is also a separate 25% off promotion w/out coupon code
In addition to the above, there is another 25% off promotion that is found on the product page of particular products. It is not stackable with the promotion above as far as I can tell.
For example, this Dolica 58mm UV filter has a price of $3.64, but when you add to cart and proceed to checkout, $0.91~ is deducted, bringing the price down to $2.73~.
Look for this magic box to see if a product is eligible for either promotion
