I have been keeping an eye out for good deals on BlackBerry Z10 (and hopefully Q10 soon) accessories on Amazon since they usually offer some of the lowest and most reliable markdowns. Their third party vendors have not failed to follow through with some great offers for BlackBerry Z10 battery replacements and extra battery charger bundles available through Amazon Prime. AmazingSteals is selling the BlackBerry Z10 extra battery charger bundle which is awesome for only $32 shipped. Yad is selling just the LS-1 second battery for the Z10 for only $18.97 shipped which is also not bad if you have Prime. Jerry pointed out that there is a non-prime offering for the BlackBerry Q10 extra battery charging bundle but its a bit pricey at $50.99.
Let us know if you spot other deals!
