Virgin Mobile cuts up to $100 off a selection of no-contract Android smartphones, with deals starting from $29.99. Plus, new customers will receive a $55 Virgin Mobile account credit with most phones. (Customers must activate a new account and top up for one month of service on the $55 Unlimited plan by July 25 to be eligible to receive the credit.) Better yet, each item bags free shipping. Deal ends July 14.

A best bet is the Samsung Galaxy Ring 3G Android Phone for Virgin Mobile bundled with a $55 account credit for $99.99 with free shipping. Assuming you'll use the credit, that's the lowest total price we could find by $5, although we saw it for $5 less in May. (Most stores are currently charging $90 or more.) It features a 1.4GHz processor, 4" touchscreen, 5-Megapixel camera, and Android 4.1 (Jelly Bean).

Update: Prices now start from $39.99.
