Was looking for a S7 Edge in my local Walmart but ending up with a s6 bundled with Samsung level box mini Bluetooth speaker for $149. I know the phone is two years old, but at this price, maybe someone will consider it. The speaker by itself will cost more than $30 on Amazon. here is the brickseek you can check for your local inventory. Good luck!
Here is the amazon link for the Bluetooth speaker

Went to another Walmart this morning and they have S6 edge instock for the same price $149. Here is the brickseek link for edge.
Samsung S6 Edge
There are many regular s6 available at price $149 but I am not interested to get, but the employee mentioned 64GB s6, so I asked her to check the price and she told me it was also $149. I think that is pretty good price for a 64GB S6. However I cannot find the sku number for this 64 GB s6, sorry I couldn't provide a BS link for you to check the inventory of this model.
******Took pictures of the s6 bundle I got yesterday and also the receipt of s6 edge, 64GB s6. Check attached photos.
