Best Buy offers the Samsung A157 GoPhone Cell Phone for AT&T Wireless for $7.49. Choose in-store pickup to dodge the $1.99 shipping fee. That's $16 under the lowest shipped price we could find, although we saw it for $3 less in August. This 2.8-oz. GSM clamshell phone features a 1.8" color display, and up to 5 hours of talk time.
