I have been using slickdeals.net for years. Use the search feature to search for a specific item you might be looking for or just use the home page to find new slick deals. Site is updated constantly. I find deals on literally everything including TVs, computers, etc. Anker items are listed on there constantly as well. You will end up buying things alot more than you do now. 
This is the best place to find new deals on cool products, or use to price match or know what an item was priced at in the past to compare.
Good luck!
