I recently found that Samsung sells the wireless charging back cover for the S4 for $39.99 and charging pad for $49.99 on their site, then found a 50% off coupon code (rv18623). After shipping and tax, I paid about $23 ea for the covers and about $27 ea for the pads! I got one set for me and one for my son. I believe the code is good through June, not sure how long they'll have them in stock. Just go to their site, select the S4, click on accessories, click on show all, and it's towards the bottom. I didn't see the set, and in fact didn't note the pads the other day when I bought the covers, but just ordered them today. One thing to note is that the pad does not come with a charger since it uses the 2A charger that comes with the phone. I'm anxious to see if the pad works with my Seidio surface case, particularly since it has the kickstand. Might have to get the non kickstand cover.
