If you're interested in the deal, skip this one and read the second post.
Earlier in the month, Samsung briefly featured on their site an S-view-style S4 case with a wireless charger in the back piece. It was $69, which seems a tad steep.
Here's the same case in white, which I found again using Duck Duck Go:
Samsung Wireless Charging Cover for the S4
And here's the black version for a much better price.
I already own a wireless Qi receiver and an Urban Armor Gear case, so I won't be getting this, but I thought it might prove useful for someone who doesn't want to have to worry about finding cases that fit receivers (or the official charging cover) -- especially at $25 less (though $45 is still steep).
