amazon's "Today's Deals" link
a trick I use, especially for consumables, on Amazon (but just about anything Amazon sells):
If you find something you want, look at the "Used" in buying choices. Look for seller "Amazon Warehouse Deals" - this is returned stuff, the condition is always under-rated and the price can be way lower. For example, bought some planer blades for half price - who wants to buy used planer blades? No one. That's why the price is so low. But they're not used...the package was opened. Also bought AC filters and stuff like that with a giant discount.
This is my signature line just so you're not confused.
