Looking to save a few bucks on your next Android smartphone? Consider RadioShack’s current promotion which sees the retailer taking $50 off of any Android purchase of $100 or more. The deal runs through July 28 for those who pick their phone up at a store but continues online through the end of August. The best part of the promotion is that it’s available to both new subscribers and existing users eligible for upgrade. Note that this does not count on prepaid smartphones.
