Slickdeals.net is an aggregate site where people from across the country share and comment on thousands of items and updates constantly.
The best way to use the site is to set it up as a bookmark on your laptop and in the morning or at night you can scan a few pages to the lowest prices for the items you want. There is also a very useful search function on the site.
The idea would be to find the lowest possible deal say on paper towels. Amazon has them on sale. 12 pack for $8.99. Now that's a steal so I use my Bitcoin preferably from a spending wallet that has bitcoin that you bought days ago that have increased in value (good idea is to look for 1%-5% for my monthly purchases.
Then stack that discount with a gift card from eGifter get the 2% and purchase the deep discount from Amazon which is over 35% off what you pay at the store.
Think about the power of using this idea with an item that is sold on Amazon and then use Purse to complete the purchase. Black Friday prices year round.
If you do this strategy long enough you will stack dollars or bitcoins whatever your preference. It might not seem like a lot but do this for a portion of your shopping and the savings will be noticeable.
