With a new iPhone rumoured to launch in September, some iPhone third-party retailers in the US have dropped the prices of current iPhone models. Now Apple Stores have offered to do the same.

MacRumors reported on Thursday that Apple retail stores in the US will match discounted prices offered by major carriers and retailers (Target, Radio Shack and Best Buy). Macworld confirmed with an Apple store representative that these prices will be honored: lucky American customers can scoop up a 16GB, 32GB or 64GB iPhone 4S for $150, $250 or $350 respectively; or an iPhone 4 for only $50.

Buyers may be asked to cite where they saw the iPhone offered for a lower price; Macworld US mentioned Target’s deal on the 16GB, followed by Sprint’s deal on the 32GB and 64GB models, and the Apple store associate offered to match any of those prices.

This deal isn’t currently offered through Apple’s online store; customers must mention this price match to an associate at an Apple retail store to benefit from this bargain.

We'll update this story when we hear if the deal is going to be offered in the UK.
