Just like Amazon, multiple, smaller retailers list their goods on Walmart.com! You will find competitive pricing and free shipping, even on some small $10 and under items.
You can also order items that are carried in the store, for same day pickup. It is great because you don't have to wanted the aisles and a 1 hour trip turns into a 5-10 minute max experience, plus you are earning money back! Win, win.
Because Amazon does not partner with Ebates, I regularly use Walmart.com for the 1% rebate, at times it will double, which over time honestly adds up! Something is always better than nothing!
