little known fact, Amazon has an outlet section for things they overstocked on (assumed demand would be higher) .

Another great way to save on Amazon stuff is to look for "other sellers" and find things that are sold by Amazon Warehouse. those items are "open box" which means someone ordered it, and returned it.

Filtering those by condition (I suggest 'Like New', meaning slight damage to the box) Can often save you from 30-75% off #sales
