I like use Amazon. I can find most of the product at 20-60% cheaper than the regular stores.
Like in Costco you can get extended memory cards with the sales and you can buy it on Amazon always the same price or cheaper.
On Amazon I can buy some tools that are 40% cheaper than Home Depot.
Sometimes Amazon does not have sell and it becomes almost the same price or more.
The big convenience the product can be shipped to my address and I don't have to go run around see it availability to buy it and waste time on the road.
Like everyone I want to save time and money so always check where would be a good buy
